Bad Precedent
I've noticed some fallout from the Mooninite scare in Boston. It seems that the police were very upset about this kind of thing going on. It seems there is a rebellious streak showing amongst the youth. Has there ever been a time where the younger people didn't want to piss off the older people? Several other cities didn't freak out. What's up with Boston?
Let's recap. A bunch of hippies want to promote a goofy (and funny) TV show by leaving light-bright boxes all over the city. This is a promotional stunt just to get attention. Hey, that's great. Those boxes are just about the size of a Claymore  mine. They have lights and batteries visible. They could very much be mistaken for bombs to someone who doesn't know what a bomb looks like. Isn't that one of the rubs though? What does a bomb or mine look like?
If I were a cop, I would worry the next time someone says that those blinking boxes all over the city are just a promotional gimmick and not to worry. People walking past will know instantly they are not dangerous.
These guys were just trying to get a message across. Think about it. All the terrorists want to do is get their message across.
