There is a definite camaraderie among Police Officers. The challenges and stress of being a cop is something that unites all officers, no matter what Police Department they work for.
Only a fellow Officer can really understand the challenges and difficulties of being a cop.
When you're working, and a call that you believed was routine goes to hell in a hurry, it's fellow Officers who are rushing to back you.
They're the ones who will bail you out of a deadly situation, and vice versa.
It's natural that a sense of cohesion develop. It's a police brotherhood which is extremely strong.
On the last day of work before days off, it's not uncommon for a shift to go out afterwards.
It's a way for cops to hang out outside of the work environment and unwind.
We'll talk about work, some will tell war stories (of course), and sometimes you'll see a couple guys get into an "energetic discussion" lol.
Police Officers are human, and even amongst cops there will be personality clashes. In many other occupations, you'll see a couple workers who don't get along for some reason and one will go to the boss and complain.
That doesn't happen in the Police Department. You don't go rushing to a Sergeant to bitch about another cop.
That's part of being a Police Officer. You deal with it without running higher up.
Even if you don't like a fellow officer for something, you can always talk off duty over a beer and deal with it that way.
There has to be mutual respect among officers, even between a pair who may not get along.
That's part of the Police brotherhood. Recognizing that even those you may not "gel" with deserve respect, and that he/she is giving you yours.
