Nixie's The One!
With the advent of the wearable
wrist drone, that just
received a half-million dollar grant from Intel, not only can one surveil and do radical selfies, but perhaps self-defense scenarios can be made much easier, or at least political demonstration countermeasures. Needless to say there are differences between "civilian" and "military" possibilities already under consideration.
If nothing else, the drive-by-knifing often used as an anti-firearm strawman, could become an everyday reality.
A shuriken (Japanese 手裏剣; literally: "sword hidden in user's hand") is a traditional Japanese concealed weapon that was generally used for throwing, and sometimes stabbing or slashing. They are sharpened hand-held blades made from a variety of everyday items, such as needles, nails and knives, as well as coins, washers, and other flat plates of metal. Shuriken is the name given to any small-bladed object, while shaken is traditionally used to indicate the well-known "throwing star".
(2013) Legal scholars are considering whether armed drones could be protected under the Second Amendment.
In April 2012, Rand Paul's nightmare seemingly came true nearly a year before he'd even gotten the chance to dream it. Four people were having a dinner party and playing cards when all of a sudden, a robotic plane showed up outside their window and interrupted their game with a barrage of bullets.
For 13 hours on the Senate floor this March, Paul railed on the government's willingness to use armed drones on American civilians, even suggesting that the government could use an unmanned plane to kill an American eating dinner with his family. But he never mentioned the possibility that the person flying the drone could be a neighbor.
