I would argue that it is actually very uncommon . . . Maybe a few highly publicized - but not "common". If you have factual numbers I will gladly stand corrected.
Oh jesus, I knew you'd get all bent out of my use of the phrase "not uncommon". I'm not in law enforcement so all I can do is speak about what comes on the evening news and I've seen more than story on this so to me that makes it "not uncommon".
