A method of disassembling a lock-down device in use by a protester may include the steps of applying liquid nitrogen to the lock-down device, wherein the lock-down device includes a connection member for insertion of a protesters arm, wherein the connection member is struck such that it fractures; removing the connection member; and unlocking the protester from the protesters position. A system for disassembling a lock-down device may include a tank for storing the liquid nitrogen; a hose for applying liquid nitrogen; a striking apparatus for fracturing the connection member; an unlocking device for unlocking a protester from the protesters position; and a housing defining a top aperture, wherein the tank, the striking apparatus, and the unlocking device are stored within the housing. |
