The Mexican "authorities", such as they are, welcome a porous border. Things are not going to get any better. Govern yourself accordingly.
Yeh I forgot to put the sarc tag on. LOL! Mexico is a failed narco state. ISIS would probably kick their azz in a fair fight anyway or more likely is paying them off.
I have predicted in the past that at some point we will have to send troops in there to clean up the mess and get the Mexican government put back together again. Would not surprise me in the least. Of course that’s if the CIA decides to get out of the drug running business.
