First paragraph of cities is irrelevant. I’m talking about Mexican gangs, not Black American gangs. Those cities are plagued with gangs formed by Black Americans.

>”Why would the border also affect cities like LA so strongly, yet completely ignore El Paso, which is literally across the river from an extremely violent Mexican city with heavy cartel influences?”

I cannot answer that for you, only speculate. I’m not law enforcement, nor am I a gang member. That’s just what they decided to do. Maybe the boarder on the US side is more heavily secured and monitored by law enforcement, so they’d have a less chance of getting caught by doing their criminal activities far from the boarder. El Paso also has a military base, Fort Bliss.
