Without addressing the actual conditions, this argument
The last poll I saw said 70% of Americans think the dirtbags are being treated as good or better than they deserve
is faulty for a number of reasons. First, 70% of Americans only know what they see on TV, so they lack the information necessary to make an informed judgement.
Second, and more importantly, consider the following (slightly) edited versions:
"The last poll I saw said 70% of Civil War-era Americans think the blacks are being treated as good or better than they deserve."
"The last poll I saw said 70% of Americans think the gunowners are being given as many rights, if not more, than they deserve."
Just because the majority says so, doesn't make it true. Your argument on this point fails.
Point two has been addressed by Ezekiel.
Point three, you claim that, of 200 releases, 5% (10 people) have been caught reoffending. Are you proposing that we hold the innocent (95%, by your own numbers) to keep the guilty as well? Given the amount of well-deserved respect Ben Franklin gets around here, I believe his thoughts on the matter are probably relevant. His thoughts? Better to let a hundred guilty men go free than to imprison one innocent.
We're
America, damnit. We're better than everybody else
because of our system of rights, and defense of the innocent, and the rule of law, and so forth. If we abandon that, what the hell are we fighting for?
