It's a class in law school that deals with what can happen if you talk to the police after an incident. Car wreck, shooting, and so on. Even if your innocent, or even the victim.
The last half of the video is in the same class, but a guest speaker that is a detective, talks about how easy it is to trap a confession from somebody. Again, he talks about even the victims getting trapped.
I started watching it and couldn't quit.
It will certainly change my way of thinking in the future.
