Well the Cuba data is probably just made up, but El Salvador is easily the highest because President Bukele (self professed dictator of El Salvador, really a right wing crypto bro who is very popular) imprisoned an insane amount of men with any vague real or purported ties to gangs on bunk charges in an attempt to bring down the crime rate. It "worked," but at the cost of imprisoning literally 1.6% of the population. Crazy to think that Louisiana is almost the same, but there's no buzz about how horrible this is etc etc. 1% of all of Louisiana is in prison!
