I lived
I lived in Mexico City for 10 years in the 90s, and during those 10 years I traveled all over Mexico. It's a GORGEOUS Country with very nice people. Also, I go to back to Mexico City, Monterrey, Guadalajara end other cities frequently for work from time to time. Yes, definitely especially in Mexico City crime rate which was already high in the 90s is even higher now, but of course it depends also where and when you hang. As a tourist is always good to try not to flash jewelry and keep always a bit alert but hey, NYC where I live is not really the safest city in the world! In some places (Acapulco, PV, Cancun etc) of course the tendency is to somehow taking advantage of tourism and tourists so it is always good to be alert, but saying that "Mexicans are some of the most rapacious people" is a big lie. Mexicans are among the nicest people I have met, and I traveled and travel the world quite a lot.
