The Daily Commute and The Daily Protest in Mexico City

"Since the city does not regulate protests, demonstrators are free to block traffic whenever they please. In just the first three months of this year, there were 740 street demonstrations, an average of about eight and a half a day - an improvement over last year, when there were more than nine a day, the city government points out.

'In our country, it is a constitutional right to demonstrate,' said Juan José García Ochoa, the leftist city government's point man for protests. 'What we can do is to mediate, so that we guarantee the right to demonstrate along with the right of free movement.'"

Currently, the government offers a daily Internet update on protests scheduled to occur, offering travel tips. The city's mayor, though, is beginning to get frustrated with the congestion.
