Red Dawn. Fantastic movie.
As for SO reoffending, it depends on the type. There are guys with sex scores for peeing on a dumpster when an old lady caught a peek. And there are sexual predators. Those defined as SP are the ones will reoffend, almost always. The others are a grab bag of maybes.
As for imprisoning for 10 years carrying illegally, and for 2 strikes your out, better open your wallets - your taxes are going up. Your tax dollars pay my salary, and all the staff that work with me. The higher the custody, the more the staff, often by a factor of two to one.
I am all for more prison space - we are overcrowded as is - not as bad as Cali, but getting there. New prison construction costs big bucks.
Private prisons? Hah, you get RAPED money wise, and they have a MUCH higher escape total than we do, not good security, high staff turnover, lotsa lawsuits, that the state pays to defend. Your tax dollars at work.
So, if you want to play the lock 'em up and throw away the key routine, prepare to either pay higher taxes, or less services. Someone has to pay me, or I'll go hang in the unemployment line, too....your tax dollars at work.
OP, nobody is killed by guns. They are killed by people who have guns and trigger fingers. OUTLAW trigger fingers!
