Mate there fuckin morons that dont do shit
I dont use them cuz there dumb shits

Cmon, u might not use them, but you would definetly wish they were there when u woudln't have them.
Just think about it. No order in society... Even if there are some dumb cops, we need them in general.
Saying that we don't need them is just dumb.

It would be like a server without admins..pretty pointless.
