In this case you can almost guarantee the dogs behaviour is as already mentioned, down to the owner more than the dog itself. The breed is largely insignificant. A dog bred in a redneck wonderland is only going to have the same attitudes.
As DiscoWeb said, I don't know what employ you're in but if anyone in a govt based position has anything like this occur then I'm sure it's in their job description as well as their common sense to report it. Both to protect themselves, their co-workers & the public from the same.
