We went to Cancun and surrounding areas ( WAY DOWN SOUTH of Mexico City, over 2,000 miles from the US border). Didn’t feel unsafe at all.
I went to Mexico City. I felt safer there than some of the American cities I've been to.

Feeling and being are different things. Criminals offend in Mexico because they have near impunity. They offend in the US despite a fairly effective although imperfect criminal justice system that varies by municipality due to the political preferences of local voters.
