All Luck (or almost all anyway, might have been one exception in the bunch)

The Keystone Cops one looks so dodgy I can't believe it was real. Somebody just happened to be recording when the robbers come running out and jump in the car, and the cops arrive just in time (and they must have been close enough to see them jumping into the car) and the cops all rush into the bank around the car as if it's not there. If that was real they all get sacked I say. Maybe even charged as accomplices after the fact
