A couple years back a friend of mine that worked at a BP gas/food station told me of an incident where two drug addicts attacked that station, one seriously injured one employee by beating him with a tire tool. This was in one of St. Louis's "most desirable suburbs". Never saw this on the news.
And there's a couple I know that moved over 100 miles out from St. Louis to escape crime because they'd been robbed. Guess what? They went away on vacation, and when they returned to their new house it had been robbed...stripped of everything...even the furniture.
People, you just have to use common sense. No where is "safe", especially if you brag or show off in public.
