Runaway Truck Hits the Federal Building

According to the guy who holds the "smile" sign at the entrance to the pedestrian walkway to the ferries, this truck started rolling backwards down the hill until the driver swerved into the brick stairway next to the Federal Building. Scary; because there are a lot of pedestrians around there and also because it's a big truck crashing into a place that's guarded 24/7 by cops who use those mirror thingys to look under every car that comes in. Funny, because for the past few weeks they've been doing work on these bricks. Seriously, there have been workmen basically taking a toothbrush to every individual brick in that wall, and they're not even finished before a truck blows down the whole thing.
