Remain calm

Deval Patrick: "There is not a reason for anyone to panic, but there are reasons for us to be vigilant."

But Patrick, Menino and Police Superintendent Ed Davis aren't saying what the things they recovered are. Davis referred to "an individual" as being to blame; said there might be more news later this evening.

Davis said police are still being vigilant around state and city buildings, hospitals and bridges.

Menino called the things "bombs" several times before correcting himself; said whoever's to blame is not going to like what's going to happen when they're caught.

One reporter did ask about the Adult Swim angle; Davis refused to answer.
