I think it depends on the offender, the day, the state, the offense, and the cop

it can go different directions depending on any of those variables (cop spilled coffee on his lap, the cheif is getting pressure from the mayor, etc. )

Here in FL, we have guys who have never had an issue, and guys who walk into the DMV (Tax collector) and walk out a suspect (in a boat theft).

I suggest you carry a very attractive woman with you at all times, and let her deal with the cop...
