Go to Juarez, it's right next to El Paso if you didn't already know. That's where all the drug wars are, and back when I was there in 2005 it had the reputation of killing women indiscriminately (

). The drug lords pretty much run the town but they won't shoot at Americans there because the CIA/Mexican Govt. will come down on their asses in a rampage if they do.
So then you should go up to some dude with an AK and be like "so y do u liek TEH DRUGS?!" Since you have like kickboxing skills or something if he gets pissed just kick the gun off of him and then grab your horse and ride out into the sunset*
