Teslaphoresis

Self assembling and able to take instructions from a distance, who wouldn't want a self aware collar and an invisible tether that would guide your steps for those long solitary walks that for now, seems optional just so long as it remains an option. Of course you'd have to be a dog to appreciate that I guess, but just so long as a tazer remains a tazer, held in the trained and capable hands of front line law enforcement, you could respond accordingly with calm gestures and so forth in case there was suddenly, a shelf life concerning those quiet strolls.. the police might simply be arriving to inform you of the latest curfew, no need to worry about any confusion here.. See? The police aren't keeping their hands ominously poised near their belts.. actually, they look rather relaxed.. Okay cool. Hmm,. well, suddenly are they frowning at you ..expressions nearly reaching a level that looks more like scowling!
The next thing you realize, you're prone on the pavement... with 40,000 volts running through you.. Seems you got tazed after all.
That was a test.
Sorry for the shock and awe of it all.
Are you okay?
Let me help you up.. sorry, yeah.. um okay.. just collect yourself as best you can and we'll hang here long enough to make sure you're back on your feet.. to wander back home.
