Well, for openers, the theory behind the Bill of Rights is of course that by protecting EVERYBODY'S rights, we protect our rights.
Second, let's get down to brass tacks. Show of hands...who's willing to have their taxes raised so that we can pay for a decent juvenile justice system? for a reasonable workload and decent pay for the caseworkers in Child Protective Services? for more, and better trained parole officers? for decent mental health clinics for screwed-up kids? for enough cops, prosecutors and judges if it comes to that? for decent rehab services for inmates, and decent monitoring so fewer loons get let out?
We've known what, "causes," most crime for well over a century. It stems from lousy communities, lousy families, hopeless poverty. It stems from a culture of violence. It stems from pathetic schools and a complete social refusal to deal in any meaningful or useful fashion with f****d-up kids, whose disastrous adulthoods can usually be seen a long way off. We've known this forever, and we do jack about it.
Personally, I think crime also stems from kids' awareness of adult hypocrisy, their absorption of a, "get it and screw the next guy," mentality from a capitalist society, and their inhabiting an urban landscape filled with ugliness.
Of course, crime also stems from the existence of large numbers of 14-26 year old males, which is a chunk of the reasons crime has been declining--their numbers have been declining. And of course, there are simply monsters, there really are--fortunately, not as many as the TV would have us believe, but they're there.
We just won't pay to do anything about it. And before you start in on, "we're overtaxed as it is," or, "they need to learn to be efficient," well, fiddlesticks. LA has somewhere between 50 and 60 percent of the number of cops they should have, and the good people of the county WILL NOT pay for an adequate police force. Or better training for them. Or decent computer networks. Or community policing. Or storefront stations. Or ANY of the stuff that we've known will work for a good long time. So, cops go out alone in cars. Nobody walks a beat. And everybody pontificates, like Darryl gates did right before he went to a big party right as the latest LA riots started....
We're too cheap. Much better to execute a few, cram the prisons with minorities, let the white-collar crime go, and stick our heads in the sand.
