A local bank got robbed last week. Bullet proof would have prevented that
A decades ago a Washington Mutual bank in SW Houston that had been repeatedly robbed installed a gated door (with metal detector) that only permitted one person to enter as a time. You’d open a door, let it fully close, and then you could open the door into the main bank area.
And it operated in conjunction with the exit door next to it. Only one of the two doors could be open at a time.
