Here’s the Lamperd video on YouTube - you must watch it. Here’s the patent for this device. The patent actually reads this:
Upon activation of the electric shock device, through receipt of an activating signal from the selectively operable remote control means, the passenger wearing that particular bracelet receives the disabling electrical shock from the electric shock device. Accordingly, the passenger becomes incapacitated for a few seconds or perhaps a few minutes, during which time the passenger can be fully subdued and handcuffed, if necessary. Depending on the type of transmission medium used to send the activating signal, other passengers may also become temporarily incapacitated, which is undesirable and unfortunate, but may be unavoidable.
Lamperd even posts a series of letters on its website showing interest in the product for use "outside of airport security," which, of course, is the real reason for the product. Why it can be used for border control to subdue illegal aliens or by local law enforcement agencies to control the "criminal element!"
