On a counterpoint.... I've been harassed by bad cops twice. Also, I was almost arrested on two seperate occasions due to mistaken identity. Also, a trooper and I had some words because the trooper didn't know the law and I did... as I eventually proved by getting a letter sent to all SC trooper stations with the SC AttyGeneral's paper on CCW in automobiles.
In a way that's kind of funny, considering that I used to BE a cop, and that I have a clean record with no felonies or even misdemeanors other than traffic citations. Nor do I live in an urban area, I live out in the country.
Then again I've had an oddly-eventful life in many other ways as well.
