Other than the white powder and the possible credit card fraud, is any of that illegal?
A detective discovered a plastic container with seven grams of a white chemical powder called HMTD, which is so powerful, cops evacuated several nearby buildings.
Police also found a flare launcher, which is a commercial replica of a grenade launcher; a modified 12 gauge Mossberg 500 shotgun; ammo; and nine high-capacity rifle magazines, the sources said.
Cops also allegedly uncovered papers about creating homemade booby traps, improvised submachine guns, and various handwritten notebooks containing chemical formulas.
The Mossberg is probably illegal in NYC unless she has a permit. I think that the magazines (sans rifle) are probably illegal, too. (Although under the David Gregory "elite liberal" exemption, maybe not.)
If the question is, "Was there much of a chance that she might actually do some harm with this stuff?", I'd guess she and her Harvard hubby were being fashionably Radical Chic and probably not.
