The police claim that the video is written to the hard drive and is write protected so they can’t be edited. My cassette tapes were write protected. I copied those. I had floppy disks that were write protected. The information was easily erased, copied, and rewritten.

The video can be paused and stopped. “Malfunctions” at critical moments in a case are going to happen. Who’s to say that the video won’t be copied, edited, and then placed back onto the hard drive? Most people won’t be able to tell right away that the video was then tampered with.

Write protection can also be easily circumvented. Anyone with access to the BIOS can turn write protection on and off. Many external hard drives simply need to be turned off and/or unplugged and then turned back on and/or plugged back in to turn off write protection. These are two examples that I have done in the past. If you search google, I’m sure there are many other ways as well.

Unless the video is time and date stamped and runs continuously, I’d be extremely hesitant to trust any of it.
