The easy solution is prison but its also crazy expensive both in terms of raw cost and societal cost (broken up families, addiction, developing gang ties in jail, recidivism, opportunity cost of taking a working age person out of the job pool).
IMO there is no politically easy solution or we would have already done it. Society has to change how it views criminals and invest resources in the things that increase the likelihood of crime. For example, rich psychopaths commit a lot less violent crime than poor psychopaths. Social services, addiction counseling, education, etc help. But its extremely hard to convince people more resources should go to helping criminals vs punishing them.
