From my experience with MS-13 in Salvador and Honduras they are pretty easy to ID. They all have giant “13”s tattooed on their chests. They aren’t hiding.
I saw a few all the way up here in Long Island NY. I work in the farm industry on the eastern end of Long Island and met a few illegals who were attacked by MS-13, one guy showing me a knotted scar that ran from his chest down to his belly. They stabbed him in the chest and dragged the knife down and incredibly he lived, and this happened here in NY. Another guy was shot in the neck just missing his jugular. Brentwood Long Island is the worst though, they were mass murdering kids until Trump brought in the feds to bust these pukes. These were all “kids” from Obamas “unaccompanied minors” scam. He literally imported MS-13 killers.
