End, that is not the impression I got from the article in your link. The impression I got is that the DC police were not monitoring the FAA. It seems as if the DC police dropped the ball.
From your link: the D.C. government was relying on a sergeant to keep track of any potential crisis. But it was not until the air scare was nearly over that he got word to police commanders.

At police headquarters, someone had disconnected a phone line that would have provided emergency communications from the Federal Aviation Administration, the officials said.
It was not until he heard fighter jets screaming past his office that D.C. Police Chief Charles H. Ramsey had an inkling of the events that had been consuming federal officials for a half-hour. And several more minutes elapsed before Ramsey received official notice and then alerted Mayor Anthony A. Williams (D).

Although police took responsibility for failing to monitor the FAA, D.C. and federal officials gave conflicting reports yesterday about what the sergeant knew at the homeland security center -- a place designed to speed communication among the many agencies that respond to terror threats. Ramsey insisted that the sergeant was not told by his federal counterparts what was happening, but federal officials took issue with that account.
In many years of work I never placed a call into the Command Center that was not promptly answered.
I was notified personally (by an FAA source) then followed up on the lead. I found and posted what I found on the web.
