I can't say about London, but Naples is an interesting town. I know a lot of napoletani, born and bread in the city and they've openly told me that there are some areas where they wouldn't even dare going. As far as Italy is concern Naples is the most dangerous city, followed by Milan and then Rome (even if these two cities are always neck to neck for # 2). It's compared to Tijuana, and the kids living in some areas have the same PTD of Baghdad's kids (read in a Repubblica article few years ago).
Luan, I realize this is your perspective, but I have to disagree with you on the comparison to Tijuana. The atrocities in Tijuana and other cities in Mexico occur on a daily basis. This incident is just as awful, but seems to be an isolated, more rare occurrence.
