Crime comes from criminals, Crime is prevented by Police, if you want this garbage to stop let the cops take off the kid gloves and do what they do. Put criminals down. I am not saying make it a police state by any means but cops are hear to serve and protect, not drive past crimes with no action. I know it will hurt a lot feelings (libtards) but let the officers do their job!
This has been tried and it has failed because those Americans who believe everything the coppers do is part of the growing Police State. Many don't want the Police involved, but they offer no other suggestions. Go into these crime infected areas and destroy the root of the problem. Eradicat the problem no differently than you would eradicate an infestation of bugs or rodents in your home.
Destroy the vermin that commit these horrible crimes against a good society!
