You hit the nail on the head. Wanna-be-jackboots & wanna-be-green coppers.
I developed a theory, real fed cops, such as the FBI, at least start out as being dedicated to law enforcement. NPS cops have no such start and as mentioned before no professional LEO chain of command.
In essence many are just psycho green nut jobs with guns. They are prime SS/Gestapo material.
Unfortunately, that is all too true. I always thought there were a lot of flunkos too — sort of like the TSA mall cops, but with more power.... They couldn’t make it as real cops, so went to the national parks. I can’t tell you how many times I was hassled — I who was another park ranger! I’d run into park visitors who were doing nothing wrong whatsoever, and hear their stories also... Sickening.
After hearing someone I’d been friends with for 20+ years justify the Tazing of an innocent dog walker, I couldn’t be friends with her anymore. Sad. The policemen I meet in our neighborhood are nicer, more intelligent, and more reasonable than my ex-friends in the NPS.
