Rule Two: Never talk to a cop or police detective. When unsure, see rule one.
Funniest thing I read was: The first line of the Miranda Warning is - "You have the right to remain silent. Anything you say can and will be used against you in a court of law." and at the end it says "Knowing and understanding your rights as I have explained them to you, are you willing to answer my questions without an attorney present?"
So right there I wouldn't say anything because the minute you open you mouth to agree they can write down anything you say. So I'd just look at them and say nothing. Not even agreeing because the minute you agree you've given up your right to remain silent. Would really upset them, wouldn't it?
