I support what he did too but I don't think it would work in the United States.

No but it would work in single states, those not commited on getting rid of criminals will sink with them into total collapse. Skill. Capital and labor would automatically leave those zones and migrate to the functioning states
The US has much more sophisticated tracking and surveillance technology to identify unsavory characters and distinguish them from others with just face tats and gang attire, but we have a completely ludicrous back end when it comes to processing and incarcerating criminals because of activist DAs and Judges setting violent criminals free.
Evil people who prey on others belong in a cage. Our crime stats show that leniency leads to increased violence, while El Salvador’s results point to more effective law and order by going on offense, despite opposition focusing on the rights of criminals, who forfeited their rights once they turned to crime, IMO
