Your recollection of what?

The best advice for anyone being asked basically anything by a cop is to tell them you aren't answeing them. You have to actively use your 5th amendment right and state you are using it. If you just say nothing at all then they can use that against you. They can't if you "plead the 5th" or tell them you aren't answering.

Loads of people incriminate themselves when they shouldn't. Any lawyer will tell you to say what I said in response to police questions.
