Something I brought up the first time this came up that no one has been able to answer.
If these 40,000 incarcerated people are such savages, then why are there only 1,000 murders a year in El Salvador? Obviously only a few hundred people at most are responsible for those murders, and half of them are still out there. So you're incarcerating 40,000 people to stop, what, 200-300 who had been killing people? Perhaps even less than that cause a lot of those shooters are likely dead already from the consequences of that life, right? How many of the other 39,800 that you locked up weren't guilty of anything at all?
People are posting about "well fukk if it's a few innocent people, I don't care about them." But what if it's not "a few", what if it's 5,000 innocent people? What if it's 10,000? There are posters here who say they want them all locked up for life and throw away the key, so are you willing to permanently lock up 35,000 gang-bangers and 5,000 completely innocent people to stop a few hundred murders a year? What if you're locking up 15,000 innocent people? Exactly how does that equation work?
Since DNA evidence came, the conviction rate in the US South for murders has dropped substantially, and thousands of people have been freed including hundreds off of death row. That's with a system that is MUCH more robust than the current El Salvador system. Why are y'all betting on that sort of casual disregard for justice and think it will ever lead to actual sustainable justice?
