Why would an American Leave America?

These days, it seems everyone wants to be an American. Whether that means they enter the country legally or otherwise it seems millions of third worlders from everywhere are literally (in some cases) dying to get here. So what would cause a naturalized citizen to flee?
Accused murderer Cesar Laurean (who IS a member of the Marine Corps, but hardly a Marine) has reportedly fled to his native Mexico to avoid being captured by U.S. authorities. No surprise there. From what we can tell, there is a pretty strong body of evidence that he may have killed another member of the Marine Corps and her (and possibly his) unborn child. These crimes are easily worthy of the death penalty under North Carolina statutes where the crimes were commited and where he would be tried. Deservedly so in my opinion. So in order to avoid going to trial, he fled across the (wide open) border into Mexico where he can hide. Now, why do I care?
Before the man has even been caught, a prosecutor in the U.S. (federal? state? who knows?) has offered Mexican authorities a deal that if he is captured in Mexico, they will NOT seek the death penalty. Why? Because Mexico, like MANY other countries in the world, do not agree with the death penalty. Because of this they will not allow the extradition of criminals to the U.S. for fear they will be tried and executed. O.K., so actually they could not care less. This is just another way to stick it to the big, bad U.S. of A. Pretty silly for a bunch of folk who continually piss and moan that we spend waaay too much time worrying about what they do. Even Saudi Arabia who gets it from all sides about their continuing treatment of women as petty property will deride us over our "barbaric" practice of capitol punishment. So here we are, with a suspected (double) murderer on the lam in Mexico and the authorities there are already holding us over a barrel for someone who hasn't even been tried. Again, why do I care?
Personally, I don't. I hope this chickensnot POS spends the rest of his waking days looking over his shoulder. Marines have long memories. So do fathers. And murder happens every day in Mexico with far less consequence than it does here. Principally, I believe this to be the biggest crock of crap going these days. We have spent decades giving and giving and taking and taking from the third world idiots lying just south of our border. (I said it!) We've been giving in terms of economic support and trade agreements to the tune of billions of dollars. We've been taking in the form of lawbreakers, gang members, murderers and rapists who continue to stream across the border into the U.S. in order to recieve free education, housing and medical care. While we are freely taking care of Mexico's prisoners (and they PREFER we never them home) we have to kowtow to these morons to get back one jacka$$ who may or may not be found guilty. We're talking about a country that lets the drug gangs own the streets in the border towns. They have billions in natural resources that go under utilized while the majority of the populace languishes in poverty. The rich have been getting richer and the poor poorer for longer than the U.S. has been around and they dare hold us over a barrel on principal? I think an invasion is in order. Once the suspect is found and jailed in Mexico, let the chuckleheads in Washington work on negotiating his extradition while a company of real Marines parachutes in to extract his a$$ to Lejune where he can face a proper military tribunal. When Mexico complains, and they will, let's give 'em a collective SCREW YOU, finish the fence and cut them off. I mean literally, figuratively and especially monetarily. Then lets extradite all the criminals they have sent here over the years. And charge them for the cost with the threat of dire consequences if they don't pay up. The time for political correctness is gone. It is way past time to call a leech a leech and charge them for their trouble. I recommend the United States become expansionist again and simply take over any country that gives us crap. Or bomb them back into the stone age. Either way is fine by me.
