As I read that I thought who would want to vacation there. But then foreign countries are like that. As far as crime in Quito, it's at least as safe as Memphis TN.
The last trip we took to MX involved armed security on an excursion to the Copper Canyon. That wasn't very comforting for me but most on the tour never noticed the security detail with M4's. The tourist industry is highly prized in most countries and the gov't makes sure it thrives. On a cruise in MX I noticed some boat patrols around the ship in the harbor.
