The two bombs that exploded at the historic Boston Marathon yesterday were contained in household pressure cookers with shards of metal, nails and ball bearings for maximum human devastation, according to AP sources. Three people are dead, including an 8-year-old boy, and more than 150 people were injured.
Dr. Alasdair Conn of Massachusetts General Hospital told the Associated Press, "This is something I've never seen in my 25 years here.... this amount of carnage in the civilian population. This is what we expect from war."
This morning, President Barack Obama called the attack an act of terror, but said investigators don't know if responsibility lies with an international or domestic group, or a "malevolent individual."
No other bombs were found in the Boston area, so investigators have to reconstruct the devices, comb through images and chase myriad leads. "We will go to the ends of the Earth to identify the subject or subjects who are responsible for this despicable crime, and we will do everything we can to bring them to justice," said lead FBI agent, Richard DesLauriers.
What is the process of the investigation going forward? If the attack had political intent, why hasn't responsibility been claimed? In the aftermath, is there any lesson to learn about security?
