A Port Authority bus slammed into a couple vehicles before crashing into the cannon at the veterans memorial in Brookline around 2:00pm on Saturday.
Surveillance video from a nearby business shows the bus making a hard left turn, hitting two parked cars before taking out the cannon and coming to a stop.
Four passengers were reported to be on the bus at the time, who said the wheels locked up and there was nothing the driver could do. One person who was in one of the parked car suffered a minor injury.
One slightly sarcastic eyewitness, Al Jones, said "man...I haven't seen a cannon this trashed since Don's last day at Channel 4".
