Situation in Mexico has been INSANE for more than a decade and it is well known to anyone who cares to look and listen, and anyone who crosses the border for any reason has to be insane as well. Cartels literally own every part of Mexico that is worth owning and control everyone from the president on down. There are not enough insurance resources in the world to get you out of there. Anyone who ignores all the warning signs and goes anyway might as well play Russian Roulette until the gun goes off. At least it will be over quick and your family will know where to find your body. If you have more things to do in this life before you die, then don't play Russian Roulette OR GO TO MEXICO. PERIOD. If you go anyway, don't expect insurance companies or anyone else to put their life on the line to come get you. The fact that rescue companies won't even go get you in Mexico should tell you all you need to know about MEXICO, and about depending on anyone to get you out of a situation you should have had better sense than to get yourself into in the first place. There are some things in life sane people just don't do, going to Mexico for any reason at all is on that list.
We were hunting on the US side of the border the day that they killed that cartel guy in Mexico. There was a steady stream of Border Patrol agents swarming the border area, more than I have ever seen, and I have seen a lot in the last 20 years. We got stopped by a Federal Wildlife guy checking licenses and tags. He told us there were plenty of javelina along the border wall road, but nobody goes there to get them. He showed us places on the map. We didn't go either. My hunting buddies/guides have hunted that area every year for over 40 years, but there are some places they won't go on the US side anymore.
