Bill Gibbons was on D&Z yesterday talking about this. The weak laws are the state's sentencing guidelines that point to diversion programs for first offenses, probation second time around and then when they finally do lock someone up the actual jail sentences are short with many times only 1/3 of time served before parole even for violent crimes. This is what leads to the revolving door effect that many of us have noticed commented on.
As citizens we need to press our legislators to change the guidlines in a manner that getting caught and going to jail is actually a deterrent as opposed to the cost of doing business. Changes like longer sentences, no parole for violent offenses, more measured use of diversion and probation for only the least of offenses, not for any violent or aggressive crimes. I would also like to see a strong 3 strikes law in place as well, if they can't shape up and fly right after two tries, F' em.
