The Washington Post has a list of 16 cities in the U.S. that France warns their citizens about, with reasons or advice to stay vigilant. The advice is generally to keep an eye out on your pocketbooks when in high-tourist areas like Times Square in New York, but it's also about avoiding areas like Harlem in NYC, Anacostia in Washington D.C., the West Side of Chicago, and Inglewood in Los Angeles (see a trend here?).
