A bizarre and (frankly) mischievous claim is making the rounds that perhaps terrorists are behind the wave of stock shorting that has caused so many financial stocks to be taken hors pistes. I’m somewhere on the other side of dubious of this claim.
Anyway, a Carl Sagan quote to keep in mind when you hear that sort of wild-eyed thing:
Extraordinary claims require extraordinary evidence.
Works for alien abductions just as well as for "Al qaeda conducted a bear raid" claims.
