They already are. Rumors are coming out that several caravaners have been killed as a warning. But the Hondurans and El Salvadorans hate the Mexicans and vice versa. They are all “racist” towards each other. Caravaners wouldn’t do the cartels bidding.
The TJ people are angry. Combine that with the cartels being upset over the border heightened security and it’s going to get ugly. Lots of info to share, as I was there last week, and talk with friends there frequently. I’m very glad they aren’t getting in.
