Reminds me of a case I once worked on.

A semi retired well known Mafiosi who settled in Van Horn, Texas. He used to drive around town (and not much of a town to drive around) with a trailer attached to his truck with a 50 cal machine gun mounted in it. Of course the gun was fixed for parade use and was not working (or at least it wasn't at one time-har har). Folks didn't pay him too much mind, just thought him to be an eccentric crazy old fool.
