Handcuffs that shocks prisoners

You know what they say – if it ain’t broke, don’t fix it. The thing is, how do you really know whether a particular thing is broken or not when the wheels of imagination and innovation have stopped spinning a long, long time ago? Do you think that there are far better alternatives to the modern day handcuffs, perhaps one that is energy based like how we have seen in some science fiction movies? Of course, what we are asking for is not for security companies or the research arm of the military to come up with a new kind of handcuff that “reinvents the wheel”, but rather, an improvement on the current design. Basically, handcuffs are steel restraints at the moment, but the future might just usher in a high-tech pair that delivers electric shocks.
