All someone has to do, is take the "at mounter", turn it into handcuffs (An item that will give you the handcuffs and a key), then mount the person in front of you. After you've done that, you have to make it so they drop all of their weapons, can't move, and can't pick up any items besides a key. Then make it so when you click, they unmount from you, but still can't do anything besides walk, and receive the key. Then you would take the key, and throw it at them, and they would be free. (The key would be restored back to the holder of the handcuffs.
