My Friendly Neighbourhood Riot Police

My small apartment is the size of a closet and it does not have Internet access -- and this has forced me to get out and enjoy Paris. So far, I've uncovered a few Internet cafes, including free WiFi at the local McDo. Unfortunately, the WiFi is unreliable. One young geek suggested that the signal is interrupted by the riot police. They are all around my neighbourhood and they are communicating with their walkie-talkies. Sometimes I feel like I'm in a war zone because of the sirens, the police cars and buses. Many streets and sidewalks are closed.
