Japan Invents a “Shut Up” Gun and I Want One NOW….

God bless The Awl. Without this in my RSS reader I might have missed out on the news that scientists in Japan have invented what is informally called a “shut up gun” – a device to silence people who talk.
Using the same effect when you talk into a cell phone that relays back your own voice on a delay, only on a larger scale, it’s fairly effective at, well, shutting people up.
I can think of about a million uses for this in San Francisco, and when these become available, I’m buying one. Muni, Supervisors, Mayor, annoying people on the street (to start) : consider yourself warned.
