Don't talk to the police

If you haven't seen this pair of videos by a law professor and a police officer on the topic of why, if you're under suspicion for some crime, you shouldn't talk to the police, you should check it out. The basic concept is that even if you're innocent (and it's likely you're guilty of something) if what you say doesn't directly incriminate you, it is likely to be interpreted as incriminating, or contain inconsistencies which would potentially seem incriminating. The police officer also gives some useful background on the various techniques he uses to get suspects to talk. Practice saying "I want my lawyer."
