Not sure how much he really CAN do unfortunately. I would say he could send out some kind of clandestine police force, but you’re a fool if you think that we don’t already have them in Mexico at full force. I’d say he could get on the Mexican police/military/government to solve the crimes.. But their hands are full as it is, what can they really do? We can’t just send our own military into Mexico. The argument could be made that this is a good reason why we need to majorly beef up border security, but the killings were IN Mexico so the argument doesn’t really make sense.
