Christine, if you're worried about the drug-related crime plaguing parts of Mexico you have nothing to worry about (as long as you have no intention of dealing with drugs). Almost all of the 34,000 victims of the violence are gang members, law enforcement officers, city officials or investigative reporters (and sadly some of their family members). The murder rate in Tijuana is on a par with Philadelphia.
