You don’t realize who players are towards each other then. Think about the toxic, horrible, and appalling attitudes that players openly exude towards one another. That is what staff deals with when players complain. If you want change, look in the mirror and work towards bettering the community, instead of blaming others for your own misfortunes.
You can walk around with a sign that says "F THE POLICE" or other stuff I guess. Here's a few pictures from another server that has proven you can implement them w/out mods:

That's not what crossfire is. Crossfire can really, only occur with controlled weapons (a gun). Suicide vests are an exception of course. But see it's not crossfire if you say hands up or die to someone in a panic room and then shoot an RPG in there. This is because an RPG basically guarantees the death of everyone in that room. While with a MK1, if you're shooting at a cop and a civ in that panic room, if the cop is behind the civ and you already engaged him, that is crossfire.
