If your intention is a standard arrest, conventional cuffs are just the ticket.
On the other hand, if you have neutralized a cell of folks that need to be made an example of, parading them around prior to an eventual execution might be beneficial to creating a controllable environment. Nothing like watching your hero contort with Tased energy.
And the 'enemy' (a.k.a. us) can't stage a rescue, because with a push of a button, you can inject your prize with a lethal dose of whatever you like.
Maybe, but I think they’d find out with that scenario, that anything you give to a prisoner, that prisoner will try to find a way to use for their own purposes. They’ll figure out a way to tamper with them and shock each other or get the drugs out, or something.
