We need a complete overhaul of society and an educated population to help reduce the incentive to commit crime in the first place, then use the wonders of the high technology we have to make investigating crimes easier for everybody so we can go back to taking control of our own streets again.

It'd take a lot of work to do it, but it's better than submitting to actual fucking fascism and tyranny because we convince ourselves we're not capable and need others to do the job of protecting each other for us.
