Professor James Duane on why you should NEVER talk to the police, especially if you're innocent:
"Don't Talk to the Police" by Professor James Duane
And a police officer agrees!
"Don't Talk to the Police" by Officer George Bruch
Note: If you ever get pulled over, there are two questions the cop will likely ask, and as a public service, I have suggested responses. The first is, "Do you know why I pulled you over?", to which you should answer, "Why?" The other question is, "Do you know how fast you were going?", to which you should answer, "How fast?" This follows along with the notion that you shouldn't tell them anything that could be used against you.
