That Spanish article you provided did not even mention MS-13.
The word for gangs is "maras" or pandilllas. Everyone in the colonia of La Laguna knows it was MS-13, because that was the gang they belonged to, and asked to get out of. They both left and went underground for 3 years, came back and apologized to the gang leader (who was in prison at the time). Now, everyone knew this, and the reporter certainly could have printed that, particularly the name of the leader. And the journalist would have suffered the same fate.
And my niece is the executive assistant to the Attorney General. They can't build a case because no one will step forward. And that, is the reason why sending them back, thinking the problem is solved, is a fool's errand. They have already started to kill witnesses and attorneys here in the states.
The policy of the United States needs to treat them as they are: terrorists and an criminal syndicate. RICO their asses. Kill them. Otherwise, they will eventually kill your family members.
Prison is only expensive because we made it expensive.
