I think that TV crime dramas do us a dis-service here. They always show people fighting with the cops, and nothing ever comes of it. The truth is, fighting with the cops is a very, very dangerous thing to do.

1. I invoke my 5th amendment right to remain silent
2. I want a lawyer
Then shut up, cooperate physically and let the thing play out.
