So, looking at that website that sparked some discussion earlier, he adds to the reasons not to talk to a police officer right away, but to talk to a lawyer first. I've heard several reasons for this: 5th Amendment rights, the likelihood that you're under suspicion from the get-go, defending your actions in a stupid way (foot-in-mouth-defense), and (the new idea) the strong possibility that your brain has blocked certain parts of the story out of your memory for the time being, as a self-protection instinct, and you need some time for your memory to sort out what happened. This last one makes the most sense to me, because you wouldn't necessarily know that your memory is scrambled, but if you give a bad story, or sequence of events, and then try to change it later, it looks suspicious. So, my question is this: I would prefer to be able to help the cops who first respond to the scene, but rule #1 (get home tonight) applies to me as well. What kind of information, if any, could I give to the police that would help them, while still exercising my 5th amendment rights?
