Perhaps you should do a little research into the actual amounts of material needed to cause casualties . The amounts are actually quite small since this was a experimental lab odds are ( GOD I hope & PRAY) they were not in possession of a more than a few ounces of the agent . In WWII the Brits detonated a small ie roughly 1 liter sized bomblet filled with anthrax on Grunard Island off the coast of Scotland.
This was a crude device filled with liquid growth media & anthrax, it was so succesful that the island was contaminated for the next 50+ years in spite of repeated attempts to decon it with bleach spray & repeated burning with napalm. The fact that the wierd beards are in fact working with bioweapons & are to the point were they are in possession of a workable amount of an agent were they can have a mass casualty “work related accident” seems to me that it is indeed an excellent weapon just that they got fumble fingered in their handling of it . HOPEFULLY this accident killed those with the most technical education as that would set the enemy back even farther .
Funny thing about the middle east - rules like “STAY OUT - CONTAMINATED AREA” are unversally ignored.
It is a cultural thing - only a peon would obey such a rule.
