If there is a lesson to be taken from the video of the "uppercut heard 'round the world," it's don't mess with bus drivers, they are apparently all very ready to stop their bus and start throwing punches at any given moment for any reason at all. At least that's how it seems after seeing the video above, shot yesterday by a passenger on a Baltimore bus, in which the bus driver is seen attacking a female student. The altercation apparently started after the driver stopped the bus to confront the girl about playing her music too loud. The MTA has suspended the driver pending an investigation.
