Sometimes it's just better to keep your big mouth shut. Years ago, a guy I knew was paying a speeding ticket and made a reference to a "kangaroo court". He spent the weekend in jail, even though he was right. I got a ticket in that same speed trap, and a few days later, the same cop and court nailed Alexander Solzenitsyn, who was passing through on a book tour. He made some remark about the cops being the same as in the USSR, but instead of throwing him in the jug, they printed the story in the paper.
