Rebar is correct. To be quite honest, D.C. couldn't exist without the huge federal funding of the city. There was never supposed to be more than a care-taker population in D.C. The civil government there is an abberation, at best. They routinely mismanage billions of dollars every year. If all of the police forces of D.C. were to stand shoulder-to-shoulder, they'd be about 30' apart on every street and alley in the city. Yet, crime is rampant.
Consider, the Secret Service patrols the White House, The Blair House, and Embassy Row. The Capital Police patrol federal property and buildings such as the Senate and House buildings. The Park Police patrol all of the federal parks, including the mall. The GPO police patrol their warehouses and areas. The Mint has it's own security, Ft. McNair, and the Marine Barracks are patrolled by the MP forces, there is also a government police force for various warehouses and other buildings. The FBI has several buildings in D.C. that are theirs to patrol, and the Post Office has both Postal Police, and Postal Inspectors.
Now, take away all of these areas patrolled by the various federal agencies, and add in the DCMetro Police, a force of several thousand. Take out the subways and parking areas, as they are patrolled by the Transit Authority. All of D.C. consists of 64 sq. miles. You do the math.
The D.C. government has a coy way to play this. Whenever they screw the pooch, they ask, and then blame, the Congress for their problems. It wasn't the voters who got the gun bans in D.C., it was the anti-gun Congress, and the Washington Post.:barf:
