In practice paying a lawyer $250/hour to sit with you while you answer questions (or not answer) is cheaper than missing out on five years of income and all of the other consequences that come with going to prison.

unfortunately the positive outcome they often have is teaching people that is a very bad idea to have goid-faith interactions with last enforcement.

Good faith and respect in interactions with law enforcement only seems to go one way, though.

Somehow, I doubt you have much "practicing" this.
