We simply focused too much on the "mass" element and not enough on the "weapons" or "destruction" components. In support of this theses I give you this story about a Pennsylvania man who faces charges of possession of a "weapon of mass destruction" after he exploded a plastic egg at a flea market. I am not apologising for or justifying his actions which, if proved, are indeed terrible. Nonetheless the WMD possession charge, in addition to the "risking a catastrophe" charge (this is a crime?), would seem to be completely over the top. Curiously he is not referred to as a "terrorist" so my guess is that he is Christian and/or white.
