Some years back, in my usual hurry, I was pulled over for speeding in a little town by a Sheriff's deputy. I don't know how it works where you all live, but in rural Missouri the Sheriff's office pays little attention to speeders... the Highway Patrol issues practically all the speeding tickets. So this was a bit strange.
Rather than the usual warning, or alternately a visit with the deputy in his car as he wrote me a ticket, he told me to get out, and then he frisked me. He found the contents of my pocket interesting ("is that a bottle of some kind?") so with his agreement I removed the screwdriver handle from my pocket and handed it to him.
Then he asked if he could search my car. I'd never been asked that before. I was driving a red Cavalier, in moderately good condition, nothing I would have thought suspicious. Whatever. So I told him, sure, go ahead.
I fix computers for a living (hence the screwdriver in my pocket) and my car has a substantial portion of my inventory of cables and durable parts in it. He ducked down and looked in the window, and decided he didn't need to search it after all.
Coda, part one: I work for a lot of counties, including the county this deputy worked for at the time. I was passing through the office of the circuit clerk one day when I heard them talking about this deputy having irritated some of the locals. Minor, obnoxious abuses of power, basically. I stopped and told the story above (which had happened only a few weeks earlier) and was told that the judge specifically ordered him to stop doing unnecessary searches.
Coda, part two: A couple of years later, I was working in the Sheriff's office in another county, when the dispatcher asked if I had met their new deputy. I was just about to ask her what his name was when, yup, THAT deputy walked in; the dispatcher introduced us, and he said he was pleased to meet me. I replied, we've met before, and he asked how, so I told him. I also said, I thought anyone who had touched me there ought to remember my name.
