Where’s the accountability that mayoral control was supposed to bring?

According to the NY Times, "Next year, the city will spend an estimated $296 million on school safety, a $5.4 million increase. In 2008, the budget was roughly $204 million."

Meanwhile, the Chancellor blames the increased spending on the police; and the Police Department (more believably) says the decision about how much to spend was made by DOE.

Where is the mayor on this? Missing in action.
