“I used to say that, as Solicitor General, I made three arguments in every case. First came the one I had planned — as I thought, logical, coherent, complete. Second was the one I actually presented — interrupted, incoherent, disjointed, disappointing. The third was the utterly devastating argument that I thought of after going to bed that night.” - Justice Robert T. Jackson

TMZ and an old photo create a stir
TMZ ran with this story this morning on a "JFK" photo that could have changed history. It got updated later in the afternoon.
It's an interesting study in how the media deals with "experts" and how the public reacts ... it was disturbing reading the over 20 pages of comments. The funny thing ... with what we know about JFK's lifestyle, it would be easy to assume that the figure in the photo is JFK.
The bottom line, for those that just can't see themselves going to TMZ ... the photo wasn't "Photoshopped." The print is probably a good but old copy from the original. So far so good. But, it's not JFK. Some comments that I have received have accused Prof. Sedlik of confirmation bias. I wouldn't go that far. There's no way of knowing what's lying on the edit room floor. I've had my own problems with being taken out of context and having words twisted and edited to fit a preconceived story-line (not with TMZ but elsewhere).
In the end, Playboy confirmed that the photo is authentic, that it ran in the magazine (in colour) in 1967, and that the people in the scene are models.

SWGDE weighs in on Research Council Reports
From Forensic Magazine:
"Since the February 18, 2009, release of the National Research Council Report, “Strengthening Forensic Science in the United States: A Path Forward,” we’ve published coverage and opinions about the report and its recommendations in the magazine and weekly e-newsletter. The 13 recommendations outlined a path, but it seems the work of clearing the brush has only begun. We will continue to follow this topic and, hopefully, the actions that will take place over the next months and years.
Recently, the Scientific Working Group on Digital Evidence (SWGDE) posted a position paper on the report that states the “report is a call to action for SWGDE to strengthen the digital evidence discipline.”
While SWGDE endorses many of the recommendations, some endorsements are with reservations and qualifications. The SWGDE response to Recommendation 7: Mandatory accreditation and certification supports accreditation for digital evidence laboratories but notes that “mandatory accreditation using the current process is not feasible for all laboratories…” In lieu of a mandatory accreditation, they recommend “that all digital evidence laboratories have a written quality management system in place to provide confidence and assurance in the quality of that laboratory’s work.”

Crime stats and work loads
Over at Media-Geek, I responded to a post asking about requests for cell-phone forensics. I mentioned that in just a short amount of time, requests went from zero to OMFG. Same thing goes for the retrieval of evidence from DVRs.
Here's a little insight from former mayoral candidate Walter Moore's blog. FBI and LAPD stats show that 22,624 people have been victims of violent crimes in LA so far this year. The number for victims of property crimes is an amazing 87,371 (greater than the population of the town that I grew up in). Add them up (who said that I'd never need math after high-school?) and you have 109,995 crime victims in these two categories through December 12, 2009.
If it takes an average of 2 hours to process a DVR at a crime scene, master the evidence, do the paperwork, and etc. ... how many people do you think it would take to handle 109,995 crimes? Here's a hint, a 40 hour work week adds up to a little over 2000 hours for the year. (understanding that not every crime was captured by a DVR) If it takes the same amount of time, on average, to process a cell-phone ... then things start to get a little crazy.
Just a little something to think about as you start your day.
Enjoy.

Body worn cameras making headlines
From the San Jose Mercury News:
San Jose police, under fire for interactions with the public that have turned violent, on Friday launched a pilot project equipping officers with head-mounted cameras to record contacts with civilians.
Officers will activate the cameras, about the size of a Bluetooth device and attached by a headband above the ear, every time they respond or make contact with a person. At the end of the officer's shift, the recording will be downloaded to a central server.
Chief Rob Davis said the devices, to be tested by 18 patrol officers, are a technological advance comparable to the advent of police cars, two-way radios and the 911 emergency system.

From the Globe and Mail:
Wearing video cameras will be routine for Vancouver police officers in the next few years, says the police chief in Canada's third-largest city.
Chief Constable Jim Chu says he favours the idea, suggesting it would be the ultimate means of preserving the truth in incidents that draw police attention.
“This is a new world. Ten years ago, you would never see video. Now you're going to see it all the time,” Chief Chu said in an interview.
“I'll give you the future: Officers will be wearing body cameras.”

Experimental Validation Tool For Cell Phone Forensics Developed
From Test and Measurement.com
"Viewers of TV dramas don't focus on the technology behind how a forensics crime team tracks a terrorist or drug ring using cell phone data, but scientists at the National Institute of Standards and Technology (NIST) do. NIST researchers have developed a new technique aimed at improving the validation of a crime lab's cell phone forensics tools. Early experiments show promise for easier, faster and more rigorous assessments than with existing methods.
Cell phones reveal much about our daily communications—the who, when and what of our calls and texts. A small chip card within most phones, called an identity module, stores this and other data for a subscriber. A subscriber identity module (SIM) accommodates phonebook entries, recently dialed numbers, text messages and cellular carrier information. Forensic examiners use off-the-shelf software tools to extract the data, allowing them to "connect the dots" in a criminal case such as identifying affiliations or detecting mobile phone activity around the time of an event.
But for this information to be used as evidence in court or other formal proceedings, the software tools that forensic teams employ are normally validated to determine suitability for use. Currently, preparing test materials for assessing cell phone tools is labor intensive and may require learning new command languages to perform the process.
NIST scientists detail their proof-of-concept research in a NIST Interagency Report, Mobile Forensic Reference Materials: A Methodology and Reification (available online at http://csrc.nist.gov/publications/nistir/ir7617/nistir-7617.pdf.) They also developed an experimental application, called SIMfill, and a preliminary test dataset that follows the methodology described in the report. SIMfill can be used to automatically upload cell phone data such as phone numbers and text messages to "populate" test SIMs that can then be recovered by forensic cell phone tools. In this way, examiners can use SIMfill as one method to assess the quality of their off-the-shelf tool."

Justices Revisit Rule Requiring Lab Testimony
Justices Revisit Rule Requiring Lab Testimony
From the NY Times
"Virginia Hernandez Lopez admitted to knocking back two shots of tequila with Sprite chasers on an August night in Julian, Calif., a couple of years ago. But she said she was not drunk when her Ford Explorer collided with an oncoming Toyota pickup truck later that night, killing its driver.
In May, a California state appeals court affirmed Ms. Lopez’s conviction for vehicular manslaughter. Her blood-alcohol level two hours after the accident was, according to a report presented to the jury, just over the legal limit of .08 percent.
But the appeals court reconsidered the case after a decision in June from the United States Supreme Court that prohibited prosecutors from introducing crime lab reports without testimony from the analysts who prepared them.
The appeals court reversed Ms. Lopez’s conviction, saying prosecutors had violated her constitutional right to confront witnesses against her by failing to put the analyst who prepared the blood-alcohol report on the stand.
But now, in an unusual move, the Supreme Court will hear arguments on Jan. 11 in a new case that raises questions about how lower courts may carry out its six-month-old precedent. Many state attorneys general and prosecutors are hoping the court will overrule its decision in the earlier case, Melendez-Diaz v. Massachusetts, before it can take root, saying it is a costly, disruptive and dangerous misstep.
“Already data and anecdotal evidence are demonstrating an overwhelming negative impact,” a friend-of-the-court brief submitted by 26 attorneys general last month said. The decision, they said, “is already proving unworkable.”
Rather than overturning the court’s June decision in the new case, which involves two Virginia cocaine trafficking convictions, the justices may simply clarify the ground rules for when and how analysts’ testimony must be presented."

Microsoft develops image DNA technology for fighting child porn
From ZDNet: "Microsoft, through a combination of efforts from the National Center for Missing and Exploited Children (NCMEC), their own dedicated Microsoft Research section and Dartmouth College, Hanover, a new next-generation technology is being launched with the aim of tacking online child abuse imagery.
Using PhotoDNA, the system picks out images which are identical, even if they have been edited, resized, cropped and edited in other ways, and logs them. The system matches them through a technique which monochromes the image, breaks the image into smaller chunks and the intensity gradients are converted into a signature.
The signatures, even through editing, will remain the same and allow the system to find copies of the original image. Some similarities could compare QR codes to this, allowing similar cells to match other images, allowing the system to recognise similar gradients and therefore image copies across massive sets of data."

SMICT standard?
"Hey Jim, I came across this acronym (SMICT) the other day, but I can't find a reference. It deals with video. Can you help?"
Sure. How's this?
From CCTV Surveillance: Analog and Digital Video Practices and Technology, Second Edition by Herman Kruegle
"7.4.3.6.2 SMICT Standard
The super motion image compression technology (SMICT) standard has almost the same characteristics of H.264. Based on redundancy in motion, it combines digital signal processing (DSP) hardware compression, with CPU software compression. Utilizing an intelligent nonlinear super motion CODEC, SMICT intelligently analyzes the motion changes in the scene that occurred within the frame, eliminates the redundant portion of the image that need not be stored, and compresses the delta (or change) based on motion."

UK announces National CCTV Oversight body
Exciting times for CCTV in the UK.
"Attached is a brief update on the announcement that has today been made by the Policing Minister regarding the establishment of a CCTV oversight body, which includes the appointment of Andrew Rennison as the interim CCTV Regulator."
I received the following in a note from the CCTV Users group:
"... Whilst personally supportive of the principal of a government body as all the devil will lie in the detail and as usual little detail is included in the briefing note, and so it will be critical for those representing the owners. managers and operators of the wide variety of CCTV systems to be involved to help frame and support the role of oversight body and interim CCTV regulator."

According to the briefing note, "The role of the interim Regulator will be to work with the National CCTV Strategy Board on six key areas. These are to:
- develop national standards for the installation and use of CCTV in public space;
- determine training requirements for users and practitioners; • engage with the public and private sector in determining the need and potential content of any regulatory framework;
- raise public awareness and understanding of how CCTV operates and the benefits to tackling crime and public protection;
- review the existing recommendations of the National CCTV Strategy and advising the Strategy Board on implementation, timelines and cost and development of an effective evidence base;
- promote public awareness of the complaints process and criteria for complaints to the relevant agencies (e.g. Information Commissioner, local authority, private organisation etc) and dealing with complaints relating to technical standards."
Let's hope they do the sensible thing .... and get the Doktor involved in a meaningful way.

Targeted Adjustment Tool
"Hey Jim, what's this new little icon on the Camera Raw tool bar?"
The button in question activates the Targeted Adjustment tool. This tool, brought over from Lightroom, makes it easy to adjust images with just a few mouse clicks.
Click and hold the button and you'll find a hidden drop down menu listing a few choices. In my example, I wanted to increase the "drama" of the clouds over this shot of the US Capitol building - taken during my walking tour of D.C. this morning.
I selected Luminance, then used the tool to click on the blue area of the cloudy sky. Holding the mouse button I dragged down (decrease) and up (increase) - using the monitor as my guide to when the image as "just so." You can watch the parameter sliders change as you drag the mouse.
The five selections available give you amazing and quick control over your edits. It's just another reason why I love Adobe Camera Raw.

More Lightroom silliness
I still get hate-mail about my stance on Adobe Lightroom. Some folks just don't understand where I am coming from on the issue. So, I'll enlist the help of another author to (again) illustrate my point that Lightroom is a database application at its core, and thus a e-discovery nightmare for forensic image analysts.
Stephen Laskevitch writes in his book, Photoshop CS4 Photographer's Handbook, "Whereas Photoshop is an image editing application, Lightroom should be thought of as a photographer-friendly database application. Instead of opening, editing, saving and then closing your image files as we do in Photoshop, Lightroom essentially uses one file: its catalog database (emphasis mine). As you work in Lightroom, it is continously updating this file. Indeed, if you look under the File menu, you will not see a Save command!"

As you work in Lightroom, it is continously updating this file. Indeed, if you look under the File menu, you will not see a Save command!"
Instead of opening, correcting, and saving individual files ... all you are modifying in Lightroom is notes in the database. If you work like most photographers, you'll have just a few databases. Some have a single catalog (database file) for their business and one for their personal stuff. Most just put all of their images into a single catalog - leveraging the power of the database functionality to inspire their creativity.
When you have to turn over your notes on the work that you've done for discovery, this catalog should be turned over - after all, it contains valuable metadata. Do you really want to turn over "notes" on all images that you work on? Hardly. What's the work around? A separate catalog for each case? It kind of defeats the purpose (especially given the lack of networking support).
Different states have different rules regarding discovery - then there's the Federal government. In response to the many e-mails that I continue to get on this subject, it's worth considering the legal ramifications of technological decisions before hand ... I would think. Shouldn't the legal aspects of a tool's use be considered during the test/validate stage - before a tool is put into general use in your lab?
And please ... I love Lightroom for personal work. I always have.

From Camera to Computer
Understanding, of course, that this is a "forensic blog" (and a Photoshop blog), part of doing good work in Photoshop is learning the rest of the trade - lighting, camera / lens selection, framing the shot, and etc. Every once and while, I find a book* by a photographer that's worthy of mention. This month's selection is From Camera to Computer by George Barr.
Here's a Canadian Photographer who started at age 12 with a WWII Zeiss Ikonta and a basement bathroom. How cool is that? The book is an easy read with a lot of depth and detail. His passion for his work is evident on each page.
The publisher lists the target audience as "Photographers." I beg to differ. There's something in the book for forensic folks as well. The first two chapters are a perfect intro into a perfectionists' workflow ... bringing out detail, balancing, and making images look their very best. The images used are a challenging start to the book's lessons.
The publisher says that "you'll see proof sheets and "not quite there" images, and you’ll learn tips on image editing from someone who is focused on creating a fine art image rather than mass producing many similar images—often the goal of commercial photographers." I agree wholeheartedly.
By now, you know my "what-how-why" focus. "With his friendly, easy-to-understand approach George goes beyond how to edit your images by teaching the whys behind the editing process. This book is certain to help you dramatically improve your own images."
By now, you know my "what-how-why" focus. "With his friendly, easy-to-understand approach George goes beyond how to edit your images by teaching the whys behind the editing process. This book is certain to help you dramatically improve your own images."
In focussing on the "why," George demonstrates his mastery of the subject. With this in mind, I'll certainly recommend this book to my friends. I think, after reading it, you will too.
*FTC compliance notice: the book was provided to me without cost by the publisher, Rocky Nook. It has since been re-gifted to an entirely worthy photographer (name withheld). I have derived no material gain from the book or the publisher whatsoever.

New Photoshop Script
Removing the word "copy" from layer copies seems to be a hot topic. I know that I've fielded a question or two about it over the years. The comments on John Nack's post are quite interesting.
If you are someone who is bugged by this, check out this new script from PS-Scripts.com. It's easy to install and use. Once loaded, through the extension manager, just launch it from the Window>Extensions menu.
It has two simple options.

Road trip
I just wrapped up testimony in a local case and am hitting the road. Next stop ... San Diego - followed by Washington DC / Northern Virginia.
There's some exciting things happening right now ... but I'm not quite ready to share.

Crime scene measurements from a single image?
"Two researchers from the University of Salamanca have developed a procedure to enable forensic police to extract metric data from crime scenes using just a single photograph. Their proposal, published this month in the Journal of Forensic Sciences, makes it possible to reconstruct a crime scene in 3D.
"We have studied an unprecedented and original line of research in the field of criminology and forensic engineering, which makes it possible to derive metric data from a single image", Diego González-Aguilera, co-author of the study and a researcher in the Department of Cartography and Soil Engineering at the University of Salamanca (in the University's Ávila offices), tells SINC.
González-Aguilera and his colleague Javier Gómez-Lahoz have recently published a study in the Journal of Forensic Sciences, which offers "a novel approach for documenting, analysing and visualizing crime scenes".
