I don't think things have necessary gotten any worse over the past few years - I'd consider them stable, as in, use your street smarts, don't be a dumb tourist, and you'll not be likely to be a victim of a crime. Oh, and stay away from protests when they are occurring. This advice is suitable for pretty much any large city in the world. Bad things happen to good people all over the world, whether or not the country charges a reciprocity fee.
