This is an article in todays paper where reporters went out and interviewed locals on their opinion about the safety of Cancun. Por Esto! | Yucatán
Interesting indeed. Let's see how expats feel: http://www.cancuncare.com/forum/living-cancun-riviera-maya/16522-do-you-feel-safe-cancun.html
Everywhere I've lived (U.S., and six other countries), the locals have talked about how they felt threatened by crime, and how it used to be safer. Cancun has been no exception to this experience. Can the explanation be simply that, as we get older, we have more we feel a need to protect (cars, homes, and family members), pay more attention to and become more aware of the crime around us; and, that as we age, we feel less capable and more vulnerable, so that without any actual change, we nevertheless feel less safe? Having the violence they direct at one another brought to our attention through the media makes us more aware of the narco mafia, and how they operate; but, does it really make us any less safe? Marginally, if at all, it seems to me, and hasn't heightened my sense of danger in being here. I'm on the streets daily, and my daily experience is enough to reaffirm that this is as safe a place to be as my home back in the states, in spite of the headlines here, or there.
