Mexico's New Terror Problem Has Nothing to Do With Cartels

On the morning of April 20, Julio César Jasso Ramírez climbed to the summit of Teotihuacán’s Pyramid of the Moon and opened fire on international tourists below.

He had arrived by Uber. He checked into a nearby hotel the night before. He had visited the site on multiple occasions, each trip a reconnaissance mission. The date was no accident. Investigators determined it was chosen to fall on Adolf Hitler’s 137th birthday and the 27th anniversary of Columbine. A Canadian woman was killed and 13 others wounded, among them six Americans, three Colombians, one Russian, one Brazilian, one Dutch national, and one Canadian. Two of the victims were children.

Jasso Ramírez fatally shot himself as security forces closed in.

So who was he, and what was he part of? The answers are chilling.
