Without law enforcement, there would be anarchy.
This statement does not back up your position in any way. When anarchistic societies have existed they have been characterized as peaceful, brotherly, loving, etc... until they are smashed out by state apparatuses. Stop repeating the words on the tv and think for yourself. The threat of force and violence impressed on us everyday by LEO is far worse than any imagined future event that might occur without police protection. Murder, rape, war are all a fact of life and will never stop. But law enforcement and police powers are institutionalized. Police violence exists because police exist. I may not be able to tell you how to stop people from being so bad to each other, but I can tell you how to end police violence at this moment: GET RID OF ALL COPS
of course what I've said is just too far out for you to comprehend
