Last I heard (10PM MDT, Foxnews channel) that anthrax incident was just some isolated freak event and not at all related to terrorism.

What's going on?

By the way, the problem with buying a gas mask to protect yourself from any sort of chemical attack is that by the time you realize that there's been an attack and you need to put it on, you're dead. So unless you're going to march around all the time wearing a gas mask, buying one is a waste of time and money.
