Not offended. I'm still reading. I don't know all the history on this gang issue. That is why I went and looked up what you posted.
Obviously I'm missing something because you are posting to me like I understand. I don't. I'm reading all I posted for the first time.
Can you explain a little more rather than assume I understand?
If I understand correctly.
MS 13 is from EL Salvador. It is a product of that country's long civil war, where left and right wing death squads fought each other and the people.
MS 13 is infamous for the extreme violence that they use as SOP, and their virtual lack of fear of law enforcement.
The Sombra Negra is a right wing death squad that are feared by MS 13 and it is thought that increased pressure from Sombra Negra in El Salvador has led to MS 13 bangers running to the US where they deal with US law enforcement which is hamstrung and emasculated by the current insane "PC" restrictions on LEO actions.
A hundred years ago these bangers would have been shot down in the streets like the mad dogs they are. By Law Enforcement.
The passage of time doesn't always mean "progress".
