Millions of people go to Mexico every year, all most all make it back. Most that do not stay there and live, after that there are a few that get drunk and end up killing them self, fewer still get in some accident, a tiny tiny bit get shot. What the press will not tell us is how many that get shot are running drugs or guns.
Sells a better story if you can blame it "them". Like 2 poor good nice Americans shot dead near the border by bad nasty Mexican drug dealers! Sells much better than. 2 death dealing American gun runners shot dead in Mexico in a guns for drugs trade gone bad. Same story gust left some info out of one. No one cares if gun runners and drug dealers get shot it is part of the job.
Happens all over the world the Press needs there story to sell. Lie, make it up, add or take away "facts", or gust tell it the way it is matters far far less than selling the story.
Best to go there and see for your self. If it feels safe to you go for it, if you hear gun shots try the next day.
