intentionally made, not to explode doesn't matter. they have all the elements of a bomb. they have power, they have a timer, they have an explosive material. so you have to take this very seriously. this may be the beginning or the prelude to somebody sending really functional bombs or it could be that the individual who put it together is so incompetent that he didn't put it together properly. but the fact is we have to take this very seriously because any one of these devices could explode and cause great damage. >> which is exactly what the officials were saying yesterday, david, that they were stunned from pamela brown's reporting, that some of them didn't explode in the multiple hands they touched before they reached the mail rooms. we know a few things. we know they were functional. we know at least one had a timer, david. we also know that at least one contained projectiles including sharms of glass. what does it tell you about whoever is behind this?
