Not everybody hates cops!
I usually get along with them quite well, and I like having them in my neeighborhood.
Samee for firefighters and military.
One of them actually decided to become a cop after I joined the military. He took the test and told me that if he didn't get on with the police, he would join the military and be an MP so he could be a cop when he got out.
Luckily he was made it his first try and he loves the work. He hates derelicts though. Occupational hazard I guess. I hate derelicts too so I never hold that against him.
I always tell him now I want his job and he says I can't have the job, but he'll trade me salaries.
