Have you noticed the 'strange' deaths of an unusual amounts of bio-weapons scientists?
No explanation to offer. Dealing with the development of weaponised bioagents MIGHT be the cause, wups, punctured the hazmat suit, that sort of thing.
If one is perhaps a bit paranoid, or otherwise doesn't trust gov't, one might alternatively take the view that discovering something useful in CW or BW is itself a ticket to an early demise.
I haven't any dog in this fight. However, there once was a weapons expert -- arguably THE expert in the design of artillery -- named Gerry Bull. The date of his assassination is a matter of historical fact; he was working for the ''wrong'' guys.
You tell me, and we'll both know, ok?
FReegards!
