A Los Angeles County jail is pioneering a gigantic cannon that shoots invisible lasers that produce a "deep burning sensation" in humans. Here's a disturbing video of prison officials shooting each other with it and giggling with horrified glee.
This reminds me of Dakota Fanning's pain-inflicting character in Twilight: New Moon, who could cripple an able-bodied man just by looking at him with her blood-red eyes. Which is to say, no, there is nothing scary about this warm and tingly joystick-operated laser cannon, at all. [NBC LA]
