If Mexico is so outraged by this "tragedy," maybe they should do a better job of protecting their northern border so their citizens don't get shot by the mean, nasty, hateful US Border Patrol.
I've noticed something in my personal relationships and career that also seems to apply to nations.
If you're responsible, then everyone else does not want to be as responsible and wants to hold you to higher standards. Its pretty darn annoying, and fairly consistent.
The US is expected to be the most accountable country in the world, probably because we are the only country in the world that regularly fesses up to anything we do, and make amends.
Our dealings with Mexico will be the same. Despite the fact they have 10 million of our 11 million illegals, and they bring literally assloads of drugs with them every year, we will be the ones to bend over and take the spankings. This is not my opinion, this is fact.
My opinion is: If we are ever going to set an example of NOT taking it up the ass, we should probably start with Mexico, our dirty little drug dealing neighbor. We need to stop policing countries on the far side of the globe, and start protecting our own backyard.
