A counter terrorism expert being interviewed on the ABC, said this atrocity had all the hallmarks of an attack by a terrorist organisation similar to Al-Queda and was probably committed by a group of people not an individual.
It is very unlikely, in his opinion, that a native American would have committed this atrocity at such an iconic American event.
These bombs may be, in your opinion, small, but they still caused considerable damage, and if set off at an earlier time, would have caused untold mayhem and human suffering.
