If something does occur, we have Thompson to blame for even suggesting such drivel!!!!
Get serious.
This topic has been discussed here and other internet forums (sometimes in great detail) for years now.
If a large scale contamination of our food supply does occur, blame the islamotrash responsible. Not Tommy Thompson.
Come on now. Let's use a little common sense.
You actually think that al Qaeda and company HAVEN'T thought about poisoning the food and/or the water???!!!
It's NOT as easy as it may seem, and can be detected early on. Besides, they (al Qaeda) aren't likely to go for killing small amounts of people, which is all that it would effect before detection would occur, they want the big numbers of deaths (bang for the buck), like deadly chemicals spread through the air over and around large cities.
No sense panicking on this kind of crap.
