Asymmetrical Information

The Wall Street Journal has

The Wall Street Journal has an article on Anthrax cases that seems to weaken the argument in favor of domestic terrorism. Apparently a letter sent to Chile from Switzerland tested positive for anthrax -- a letter identified as suspicious because while it was postmarked Switzerland, it had a return address in Florida. From what I've seen of the domestic crazies, they have neither the resources nor the inclination to zip merrily around the globe, mailing letters hither and thither. On the other hand, it is only one letter, and there is no word on whether the Chilean strain matches ours, so perhaps it's a wash.
