I think we should honor our extradition treaty with Mexico as well as they honor the rest of their treaties and laws.
It took a genius like Chapman a couple of days at most to find the scum. Mexico had no intentions of finding him, they never even tried.
Hell, I'm no fan of Chapman, but I'd refuse to extradite him and tell Mexico to go pound sand, just on general principle. Mexico's dealings with the U.S. are about as stand up and straight forward as North Korea's. Hell, they try to tell us how many of their people we should accept, and we should have a completely open border. And they think we should honor an extradition treaty? Sure, when they stop the drug smuggling and illegal aliens crossing their border with us, and stop letting their "police" and "army" violate our border. In other words, right after Hell freezes over.
