You've summarized it nicely. Those who don't want to be recorded are part of the 95% that give the other 5% a bad name.
I could figure one of them out. I had tried to place a long distance call from my home phone, but dialed “9” first, like I was on the office phone. Never figured out how a second one was placed.
OK, I can remember at least two instances where the officer had obviously just broken up with his wife, or something. But even then they had me dead to rights, wrote my ticket, and let me go on my way with no trouble.
Of course it helps that I treat them with respect, have no criminal record and no outstanding warrants against me, and am fairly well into “late youth” (I'm currently 67).
Still, they have a right to tape any encounters with the police.
