I actually agree with you on some of these points, except the job parts. People do get fucked, and it is a 2 way job. Some people do it for genuine reasons, others do it for the power. If it makes you feel better, the power hungry guys normally aren't well liked by other cops, and rarely last more than a few years.
None of those jobs really get shot at ever while working. Yes, they are dangerous though, but the only one i really agree with is fisherman. They can't control what happens out there with the weather etc. But the rest, if something goes wrong, it's going to be someone's fault. If a metal worker falls off a building and dies, he probably fucked up his safety equipment, or just neglected to use it. He wasn't just pulling up to a domestic disturbance call and got shot for no reason at all, other than who he is. Pilot is hardly a dangerous job anymore, but people seem to have this 1920s outlook on it. Pilots hardly even fly the planes anymore, its mostly autopilot. They come in when the shit hits the fan. And once again, most crashes are pilot errors, which happen despite the immense amount of training they get. (my brother is a pilot) And i have little idea how truck driver is more dangerous than cop. Sure...they drive a lot, more potential for accidents, but they usually get into accidents when they've broken the laws on limits about driving per day. If you've been driving for 30 hours straight, something bad is probably going to happen.
You guys need to deal with real cops, not suburban cops who are often douches. My dad works in the worst section of his city, with countless gangs and murders. (i actually got a picture txt this morning of another murder) He's been shot at more times than all of you combined, and he's never been hit. He's been stabbed, gotten into countless fights, and in general beaten the shit out of half of the city's gang members. This type of cops are not douchebags at all. For one thing, because they don't do a lot of traffic work, so no BS tickets or anything, instead they just get the worst of the worst. These are the humble guys who don't deal with the stupid shit, just the murders and gangs
And your last part, about cops bonding together, thats something the media portrays. If a cop fucked up, the first ones to tell him that will be other cops. The department is just trying to cover their ass for the sake of their reputation. That cop that fucked up is screwed though, because he will not be liked by others if it was really his fault, and no one will want to work with him.
and i'm sorry that was so long
