F.B.I.'s Anthrax Inquiry

To the Editor:

Re: "The Deepening Anthrax Mystery" (editorial, May 11):

Far from "bureaucratic bungling," this complex investigation represents a case study in cooperation between the scientific community and government agencies.

Analysis of the powders collected from each letter has determined that all are the same strain.

There were differences in the samples recovered from the letters mailed to New York and those mailed to Senators Tom Daschle and Patrick J. Leahy. But there were no significant differences in the samples collected from the Senate letters, and there was no increase in potency or improvement in quality from one Senate sample to the next.

You say "the F.B.I. remains convinced that the attacks were carried out by an American with scientific training, not by Al Qaeda or a rogue nation." In fact, we have not precluded any category of suspect, motive or theory.
