I know this isn't apples/apples, but consider that many places in Texas are 300-400 miles from Matamoros while Cancun is 1400 miles away from Matamoros.
Also, and I am in no way defending cartels, but the cartels aren't exactly targeting tourists. I found it surprising and odd that the cartel issued an "apology" and "turned over" those responsible (probably a lie), but that made it clear that they have no interest in killing tourists. The market is a bigger force than they are and they know killing tourists is bad for business. Which is why you dont see cartels causing much trouble in the big tourist spots, aside from the fact that there aren't many tourist destinations along the US border.
a big exception to this is Acapulco which used to be THE place to go. but generally when I go to Mexico i feel nervous before I leave, but when I get there I wonder what i was so scared about.
