Do you think that the fact that many Moslems work there at Hanford (see post # 1,110) poses a national security risk for the US?
Not necessarily by virtue of religion, no. However, anyone with a pulse can get hired there, if they don't mind blistering summers and miserable winters.
I see your point, but Hanford is such a large facility (federally administered, for what that's worth), a low-level disgruntled fanatic isn't likely to be able to carry out a catastrophe, at least not without quite a few bureaucratic foulups and a bit of inside help.
