Horrific, the Mexicans now believe that most of these people were illegal immigrants from Central America who refused to work for the cartels ... the cartels force the illegals carry drugs in exchange for their help getting across the border, those who refuse are killed. People have to understand that we arent dealing with some harmless band of comical "Banditos" shooting pistols in the air ... these drug cartels are extremely violent and will kill anyone who stands in their way without hesitation. This is rapidly becoming a serious national security issue for the United States and it seems that nobody in Washington is paying much attention.
Another issue is that historically the Mexican government has less and and less control the further away you get from Mexico City and this is especially true of areas along the US border and the Guatemalan border ... look back on history and you will notice a pattern regarding revolts and major violent outbreaks in Mexico. Mexico has never had a government that has actually controlled the entire country ... even the legendary strongmen like Santa Ana and Proifero Diaz couldent even control the whole country. Hell even when the Spanish ruled Mexico they exerted practically no control over the area that is now the southwestern United States and the northern states like Sonora, Chihuahua, Baja California, etc. This doesent even address the corruption and mismanagement that has also traditionally been a huge aspect of Mexican politics and law enforcement.
My whole point is this: we have a huge problem on our southern border and it needs to be addressed before their problems spill over to our side of the fence. We are seeing the same kind of lawlessness and violence that took place during the 1910-20 Mexican Revolution. It's deja vu. All we need is another Pancho Villa and we are all set.
