Excellent. If we disband and abolish police forces, and arm every competent adult, I think the violent crime rate would almost completely drop off the map. I might be wrong, but in light of the current situation almost anything would be better than what we've got. The state has killed more People than any other single cause including religion and war.
Similar arguments could by used toward disbanding EVERY federal agency, bureau, service, commission, and committee that has no Constitutional existence. For instance, the FDA has killed more people, through actions which have no Constitutional basis, than they have ever helped. They spend their time policing free speech, suppressing testing and promoting of bonafide cancer cures, and stopping People who want to from drinking raw milk, all the while licking the butts of the corporate interests from which they are supposed to be protecting the People.
