No matter what you say, whether you're innocent or not, you should NEVER talk to the police. Something will incriminate you and many people are afraid to envoke their 5th ammendment right. But I've listened to a very informative speech by 2 people, Law Professor James Duane and Law Enforcement Office George Bruch. They've done a great job of explaining from both perspectives, why it's never a good idea to talk when being interviewed or questioned. Listen to their presentations and you make your own decision, but I no know why I won't be talking. (Hope I'm never in that position though.) Even if you get a speeding ticket...shut up.
