I'm sure they are. Have run across a couple here and there over the years and not a single one of them had anything good to say. Most of the rail workers would shoot the shit with you and just say "as long as your not shooting our signs we could care less" but put any kind of authority in the mix and it was always a PIA lol.
Good friend of mine use to work for Norfolk in the rail car department and he never had anything good to say about the investigators either. He always made fun of them lol.
The railroad dicks are just that. We used to walk the tracks mid week of gun season a run the sht out of deer. Those guys have nothing but time to fugg with people
