Almost every argument I've heard against this guy starts falling apart when the person speaks about the mega-prison as if it was a bad idea and should not have been done.
El Salvador was completely cooked and he actually made a good point about saying the whole country was in fact imprisoned by these gangs, the place was a fucking hellscape and you had a lot of people who are just violent psychopaths that belong in jail forever.

I've got no doubt some innocent people are locked up, or that some ganglords have exchanged everybody under them to keep themselves out of prison, but the alternative was simply so awful as to all but demand the most radical solution.
