I would do a lot more than just send FBI help. I would say “Killing our consulate people is an act of war!” and if the Mexican govt. wasn’t in a position to help, send in the SEALs.
We need to close all our consulates and bring all the U.S. citizens back to the U.S. Then shut down the friggin border - if necessary by putting a member of the armed military every 50 feet and let no one cross again. Then start a sweep for illegals on the northern border and send them and all their drugs back across the border. Just how long do we have to put up with the stupidity of our own government.
