Would you take a suit case with a bread bored, exposed wires, and a 9V battery through security at an air port? How about higher security areas than that?

There is a very, very big difference between what was worn and something that one would associate with being a light up sweeter.

When I heard the story I assumed this ( http://cdn.shopify.com/s/files/1/0070/8002/products/g513a-ch... ) was what was being worn.

There is a big difference between exposed wires, batteries, with blinking LEDs stuck together on a breadboards and Legos. When going to an area with elevated tension, security, and crazed guards the gap between "weird" and "threatening" is quickly closed.

Yeah, that's kind of my point. Incidents like this aren't about safety, they are about conformity.
