Its an election year. If the Democrats push a terrible law that seems "tough on terror" and Republicans vote against it, they get to spout off that "Republicans voted to allow terrorists to buy guns". In fact, that is likely the point of the entire exercise; getting an election year catch phrase. Its the same as the "voted against body armor for the troops" charge leveled against people who vote against omnibus spending bills that cover gold brick projects.
This whole PB thing riled me up because it reeks of the Sherman tank "scandal". The Sherman was terrible and got people killed and only stupid generals wanted it! Well, no, not the case at all. PB was terrible and gave people GWI and only stupid generals wanted it! Well, no... they remembered all the media outcry about the Sherman tank being insufficient protection or the M113 being too thinly armored or the Bradley armor plating being flammable and weren't about to with-hold pharmacological "armor" from the troops. And with a 1mg droplet on your skin being a lethal dose... I mean, that's less than you or I get from a close proximity sneeze, or even handling a doorknob. These chemicals were formulated to kill a tank crewman who drove through a contaminated area and then touched the tracks. Pretty radical measures become reasonable against chemicals engineered to kill humans. The CDC's spill guidelines for 50 gallons of the stuff called for evacuating 2,500 meters in all directions to 10,000 meters downwind. Imagine 500 gallons of aerosol from a Scud bursting over a division's axis of advance and you start realizing the nightmare scenario those pills were prescribed for.
Anyway, I'll lay off for a bit or I'll be here all week.
