Yesterday, Attorney General Eric Holder announced that Dzhokhar Tsarnaev - the surviving suspect in the Boston Marathon bombings - is being charged with using weapons of mass destruction.
The WMD is that pressure cooker bomb, loaded with nails and ball bearings, that killed three spectators and injured more than 180 others.
But while the harm that the bomb caused is undeniably high, is the bomb, in fact, a weapon of mass destruction based on our government’s definition? And if so, what else falls under that definition?
