My scenario (having no knowledge of the facts is that a career as a cop caused a mental disorder that rendered incapable of coping with total open disrespect.
This question should cause us to ask what we can do to change our culture of how cops are treated that causes them to suffer from this.
Its also related to the high unpunished rate of spousal abuse by cops.
It’s not how they’re treated, at least here in Canada it’s how they’re trained. It’s us vs them attitude now.
I had a consulting job with a metropolitan police department in one of the largest U.S. cities. One day I was out on a highway overpass with one of the police lieutenants discussing possible photo angles for some public relations stuff. Police had shut down two lanes for the protection of some workers on the roadway, and a lot of traffic was being funneled into the other two lanes. I saw huge muscular truck drivers lean out of the cabs of semi's and either curse the police or flip the bird right in their faces. It astonished me, but the lieutenant said, "It happens all the time. You just have to ignore it." He was a home town working class guy who had sent himself through school and then law school at night, so it's not like he felt he was socially insulated from this abuse. He simply had become a professional.
