Regularly I hear of American who are concerned about trips to Europe due to the fact that there was a recent terrorist attack of some sort. They want to know if it's too dangerous.
I always just want to ask these people if they know anything about the country that they live in? I'd run around the supposed Muslim no-go zones in Paris (no they don't exist) carrying a massive racist anti-Muslim cartoon sign and still feel safer than I would going to a Florida Wal-Mart.
