A couple things I feel are lacking in warden training seems to common sense and treating the public at large with respect. I know it often takes a couple years for the 'new' to rub off some of them. One of the most disturbing shows on TV is "Wardens", the amount of ignorance and ignoring of Constitutional rights is scary. (For instance I recall one episode where the warden orders a member of the public not to mention to other hunters he is there doing checks...all sorts of things like that are shown.) Everyone is assumed to be a law breaker and a threat from the jump. Even though most of us have never intentionally broken a law and take the regulations very seriously, condemning anyone that does not.
I did unfortunately live next to a turd of a Federal warden a few years back, and the guy was absolutely insane, pulling a gun on my wife twice, depositing a dead cow right next to our yard but just across the fence...all sorts of crap because we had a legal easement he was not happy about a judge upholding. Reporting him to any LE agency never did anything but get a "we will talk with him, he's under stress etc". Thank God the idiot died at 50. Not many people I would say that about other than Chavez.
Luckily the worst are normally found out and replaced as the guy from Hardin was a couple years back.
That said most I have known are decent and fine people, just that the bad apples are protected.
