When I see these thugs with MS13 tattoos on their faces, it's a pretty good indicator I can determine their identities. Yes, you can judge a book by their cover, and yes these people are outright criminal cartels that need to be made into tractor food. Kill them all and let God sort them out.
What you’re advocating is not just taking the law into your own hands, it isn’t even according to natural law or justice. It’s just murder. And if you act accordingly, you’re not going to like it when God does the sorting out you speak of. After all, He is the one who said not to commit murder.
