I can’t remember haw many years ago it was discussed here but at one time the left once vehemently denied that MS-13 even existed. They claimed it was all just right wing anti immigrant paranoia.
When President Trump mentioned them many lefties still tried to act like they didn’t exist. That blew up in their faces because there has been some high profile MS 13 crime, like the murders on Long Island. Once again the media plays games, they have reported about MS 13 crime but then like to act as though they don’t know about it.
