Why, have you never remembered an event wrong?
Sure I have. So what? If police misremember the event, is that somehow not relevant?
The behavior of everyone will be plain to see on the video
That was actually caught on video, that is. As I explicitly pointed out. I spoke - direct quote here - about the ability "to craft a story that fits what was recorded, and leave out or invent things that weren't picked up". What happened before, or just offscreen? Police are known to claim that someone was "reaching for a gun" - even when it didn't happen. But if the camera angle is bad, they will know they can claim that regardless of what they actually remember.
every lawyer knows the trick of picking out one detail someone got wrong and spinning that into proof that everything they say is a lie
But... but... if "The behavior of everyone will be plain to see on the video", how could a lawyer get away with that?
Frankly, I consider that a feature, not a bug, anyway. Eyewitness testimony really is ureliable. 'Bout time juries learned that applies to police too.
