u.s. embassy mexico travel warning the real problem nobody wants to admit. Just read that the U.S. Embassy in Mexico is warning tourists about cartel violence again. Well, wake up, people! It's common sense that if you go wandering into dangerous neighborhoods looking for cheap tequila and Instagram selfies, you're asking for trouble. I live in a border town, and I see this every day—folks ignoring local advice and then crying for help. The embassy can't babysit everyone. Stay in your resort, respect Mexico, and use your head before blaming anyone else for your poor choices. That's just common sense.
