In reality, PP has NEVER been subjected to any kind of attack with anthrax.
There have been a number of hoaxes that they most likely perpetrated, but not a single spore has ever been demonstrated to have been sent to them or their friends.
What is most distressing in the debate you are having with the other fellow there is that you know this, and he knows it too, and I know it.
PP has not faced a single real instance - not one!
