The carceral state of El Salvador
Naughty girls and their bad prison boyfriends
"Mara Salvatrucha" a.k.a. "MS-13" is primarily a Salvadorean gang. El Salvador has been fostering a criminal gang culture and lifestyle throughout the country — with a life of crime and prison effectively the only option made available to boys growing up.
The name, in a partially rhyming Spanish cant, translates roughly to a little ditty or saying "Mary, save the trout!" which makes perfect sense among criminals of a predominantly Catholic culture. Notoriously corrupt cops are said to be "fishing" and the trout is the suspect, a fellow gang member who is under investigation or indictment, which might bring other gang members down, if the investigation or indictment is not bungled or sabotaged.
The cop-go-fishing and mary-save-the-trout ditties explain why cops with MS-13 tattoos are not considered gangsters among their fellow cops. Cops cannot be members of that gang, and on a cop, such a tattoo is interpreted as a mark of a hit or token of some victory against MS-13. There are tattooed cops, but, well, cops are cops in a certain sense with respect to that particular gang.
Cops in gang-ruled jurisdictions are put on drugs and alcohol and given a "tackle box" with too much fishing gear, hooks and lines that are easily fouled going after criminals.
"Coronavirus" was coincidentally renamed to "COVID-19" in the exact same manner by the exact same gang, which has obviously gotten into medical malpractice along with other serious organized crime.
