‘Mexico City has been a haven of peace’ — after reading this statement, I knew the rest of the article would be hooey. We were in DF 20 years ago, passing through to Merida. I wanted to stop and visit a home where I had lived as a student, and it was a very scary ordeal. NOT safe then, even less so now.
Of course you are right. I've spent plenty of time in Mexico City (Day Effe) from more than 20 years ago to the present, and it was always a dangerous place, kind of like NYC was back in the '70s. It's different now, just like the article says, it's a different set of more serious dangers. It is very sad what is happening in Mexico, and it's going to be sad for us when it comes north in the not-too-distant-future.
