I recently testified in one of the most involved, and important, cases of my career. I was confident in my testimony because my client lawyer and I spent time preparing and rehearsing my testimony. While waiting two days for my turn to testify, I continued to review my investigative notes, and all other work products I created. At that point, I was completely familiar with my findings, all reports and materials used for the case.
The day before I testified, I discovered the only way to access the video projector and sound
system in the court room was through a downloadable software program created by Epson. This software was something I had never encountered for playback in the courtroom. An important detail that my client attorney had not mentioned to me as he knew about it prior to the trial. I had no idea; this was a first for me. In hindsight, it was my job to investigate sooner. Even as an Audio and Video Forensic expert, on site learning objectives can be troublesome, especially when your head is so far into preparation for a expert witness testimony. Lesson learned.
My client attorney forwarded the information from the A/V department of the court, which was a link to download the software program. They asked what operating system I was using and I told them Windows 7. He forwarded the link and I downloaded a zipped file. He told me to meet him at court at 8 AM the following morning, which I did.
I arrived the next morning, met the tech, and he instructed me on how to properly install the software within my Windows 7, Asus Laptop. He told me he was not allowed to touch my laptop. As an Audio and Video Forensic expert, I have extensive experience with technical issues experienced on a computer, but this was a very difficult process.
We launched the program and connected my laptop to the projector. My desktop was now viewable and I took a sigh of relief. Then I discovered none of the forensic applications I use while presenting my investigations in court– Adobe Audition, Premiere Pro and Sony SoundForge – would open. One of the first skills I learned firsthand in the technical support department was that if something isn’t functioning correctly on a computer, go back one step and reverse the most recent changes made to it.
So I informed the judge I was not ready, and the lawyers decided to proceed with some other portion of the trial while I troubleshot the issue. Court began, the jury was brought in, and I unplugged my laptop and snuck back out into the hall. The representative from the AV Company was going to leave and I asked that he stay just in case. He agreed and for the next half hour I began to make my steps back to square one. That’s when we realized: the Epson software assumed ownership over my Sound & Video Card so that it could operate the projector, leaving all of my normal forensic display functions inoperable.
After the last bit of junk was removed we re-booted my laptop and everything worked. I was relieved, until I realized: I didn’t have a projector. I looked at the tech and asked if there was an HDMI input that we could run a long cable to. He said yes, but we would need a ladder and a long cable, which he did not have. He remembered he had a small data projector in his truck. We tested it in the hall and it worked.
Next, we had no cart to put the projector on. We noticed a small antique table that was holding a pitcher of water and some cups in the hallway. This was a very old, historic courthouse, built in 1847. I bet that table had been there for a very long time, because when I moved it the legs were wobbly and the judge – very sternly, almost scolding – told me to lift the table when moving it.
I put the projector on the table, got it positioned, and moved the lectern close as the VGA cable was only 6 feet long. The jury had taken a break and the judge was really rushing me into being ready.
As if this wasn’t enough stress, the prosecutor came over to me and started asking me questions, and ‘my’ attorney was out of the room. She was definitely out of line, and if I would have said anything, Lord knows what would have happened. So I told her I was not able to talk to her. She was very emphatic about wanting to know certain aspects of my investigation that were well covered in my reports. I ignored her and finished setting up as we heard ‘all rise’ and it was just one of those moments that you close your eyes and ask God to help make sure it all works. Everything came on and I remember hearing my ‘boot alert’ on my computer chime through the speakers, and I breathed a sigh of relief as I saw my desktop on the projector screen.
As digital media forensic experts, it is our responsibility to test all presentation tools (software, hardware, images) before testifying in court. These tools help judges and juries understand the facts about our investigation more effectively instead of using just words and reports.
Even though I was told by my client lawyer prior to testifying that the court had a data projector and sound system, it is ultimately my responsibility as the expert to test everything in advance to avoid any technical glitches. That way I would have plenty of notice about introducing an unexpected piece of software (that completely took over my computer) well in advance, instead of minutes before testifying. Interruptions of the technical variety have the potential of distracting us more than the unexpected off the wall questions of a prosecutor.
I chose to publish this blog post so that lawyers and forensic experts understand the importance of technology in the court. I also wanted to share my experience with problem solving in case you are challenged with a similar technological glitch prior to testifying. Stay calm and think logically in order to stay focused and get the job done.
