In the just-released issue of the Metropolitan Police Department’s newsletter, the weekly mag trumpets decreases in aggressive speeders caught by redlight cameras:

For the sixth month in a row, the rate of “aggressive speeding” on roadways monitored by photo radar cameras was less than 2 percent during January 2007. Just under 2 percent (1.8%) of all vehicles traveling through photo radar enforcement zones in December were found to be speeding aggressively that is, traveling above the threshold speed established for the program. That rate is just slightly higher than the record low rate of 1.7 percent, which was recorded in August 2006. During January 2007, more than 1.7 million vehicles passed through enforcement zones monitored by the District’s stationary and mobile photo radar cameras, but fewer than 32,000 were found to be speeding aggressively.

Maybe this is why.
