At Trenton it wasn't the dimwit Feds who acted -- it was the local Mayor and the postal workers. They decided to get tested on mass and arranged it.
Thank G-d they didn't any longer for the *all-knowing, all-caring* federal government and postal service to act!
correction: ... didn't wait any longer ...
And just where did these letter orginate? Trenton. Which means exposure may be even more important to the testing and the investigation (get it - catch the guys(gals?) before we have bigger problems!
It's time for these guys to quit "following the science" and jump in front of it!. Our national security depends on action, not reaction.
