Well we're gonna have to agree to disagree. There is no justification to kill unarmed civilians, doesn't mattter where it happens or what excuse is used. This sounds like Israel using Hamas to justify killing civilians. So here 'criminals' are the justification. Same exact thing because people who aren't these criminals you speak of will certainly suffer more than these alleged criminals. Its the playbook of every tyrant throughout history.

Tell that to Salvadorians
No one is advocating for the killing of innocent civilians. It’s always the people that don’t live in the thick of it that all the sudden care about humanitarianism now that there is change in leadership. When criminals terrorized the streets for years none of these Monday morning quarterbacks said anything.
If it were up to them they would still have MS13 terrorizing salvadorians.
