Of course it was in Boston where the cops all went bonkers because someone was carrying around some wires and LEDs (via Bruce):
Star Simpson was charged with possessing a hoax device today at Logan International Airport for wearing a sweatshirt that had a circuit board affixed to the front with green LED lights and wires running to a 9-volt battery.
This is not a bomb:

And furthermore, being the nit-picky engineer that I am, it's a breadboard, not a circuit board.
If someone wanted to carry a bomb around at the airport they would almost for certain put it in a suitcase instead of wearing it in the open on their sweatshirt. And since it was in the open you can easily see there is no detonator and no explosives attached. But this is Boston. And so:
Outside the terminal, Simpson was surrounded by police holding machine guns.
"She was immediately told to stop, to raise her hands, and not make any movement so we could observe all her movements to see if she was trying to trip any type of device," Pare said at a press conference at Logan. "There was obviously a concern that had she not followed the protocol ... we may have used deadly force."
Simpson was arrested...
Bruce says Refuse to be Terrorized. I say Boston was just exercising their authority as a police state. And the police probably hadn't gotten to play with the sub-guns in weeks. They had to justify having their toys by actually pointing them as someone occasionally.
I do agree with Bruce that the true terrorists are probably laughing at us.
