@ossobuco,
Sure Zetas are real. I have family in Mexico, in fact I have family in Cd. Juarez (widely known as the center of the drug war). I know about the Zetas and what they have done to Mexicans.
I also know that they are not a real threat to average Americans. Even along the border, very few Americans are getting killed. This is a big story in Mexico. This is not a big story in America (except for those of us who care about people in Mexico).
This lie (and it is a lie) is simply a very convenient way for racist hate groups to get people who don't want to be racist riled up against Mexicans.
There is a real story here, if you care about the people (i.e. Mexicans) who are suffering at the hands of the Zetas.
Of course, the real villains in the story are the American customers... who keep the Zetas in business supplying them with obscene amounts of money and selling them guns.
If the real story were posted, instead of the hateful exaggerated lies of hate groups, I wouldn't be so upset.
