So now a pressure-cooker bomb is a weapon of mass destruction?

Surviving Boston bombing suspect charged: conspiracy to use WMD

He was charged in federal court in Boston.

Not clear whether this is because he is a citizen or because they don’t think he’s covered by the authorization for the use of force, or for some other reason.

When I was in the army during the Vietnam War they taught us that WMD included radiological, chemical, and biological weapons.

Not plain explosives, bombs, or whatnot.

But usages change and this is a question of legal meaning, anyway.

He was not charged in connection with the deaths of the policemen they killed.

I suppose those would have been tried in the Massachusetts state courts, and that state has no death penalty.

But perhaps they will have a go if the kid is acquitted in federal court or doesn’t get the death penalty.

Or in any case, but after the feds are done with their trial.

As for that special questioning by that special FBI/CIA team, looks like it didn't happen or it took about five minutes.
