Perhaps, but what do you think of the Al-Qaeda, testing for major terrorist attack

The "test" theory is one of the more idiotic repeated FR theories that you see around here; repeated over and over again, and most popular with people that are frustrated and disappointed that with the hundreds of thousands of them pure-evil Mooslems in this country, they sure don't commit as terror attacks as you'd expect if they were all terrorists.

Thus, everything that MIGHT have seemed at first to be a terror attack but turns out not to be, gets proclaimed a "test."

Which makes absolutely no sense from a practical terror standpoint; "Dry Runs" such as the 9/11 terrorists did before their attack make sense, but making "semi-attacks" makes no sense whatsoever in terms of the terrorists learning anything at all, and in terms of alerting targets.

I remember several incidents of evacuations of grocery stores in the Dallas Fort Worth area. It just seems to come and go. Usually three or four incidents then it disappears.

Arlington TX was hit with a couple of these events a few years ago. Customers complained of a foul odor and fainting. I'll see what I can find.
