What stands out to me is the complexity of the attack. To make an explosive for one take a lot of knowledge and logistics. To transport the explosive means the individual(s) was sure enough hat it would not detonate prematurely. The selection of the target either means the person(s) is a local with extensive knowledge of the area or it was scouted out in advance. The functionality of the "Warning" message is not something everyone can do. Is it something a loner could pull off without raising suspicion? Possible. But not likely. Normally loner type Bombers start off small and build up. A group of 2 or more are most likely capable to pull this off. Motive, remains to be seen. But for sure, one part of the motive is to "terrorize" the public. Lets not be fooled just because he had a "warning", that this is not a terrorist event. This is not a Robin Hood bomber. My bet is it is either some sort of Cult based attack or a politically motivated attack. Or both. If the AT&T building was the target, why? What symbolism would that carry for the attacker(s)?
