But this law professor gives us 8 reasons to say nothing. The video is long, almost 50 minutes, but the first 30 are a law professor explaining why, in great detail, that you never speak with the police except to ask if you are free to go or to ask for a lawyer.
The best part, the second part of the video is a police officer backing up every single thing being said here. Also explaining "interview" techniques and such. Long video, but very worthwhile.
