This is interesting -- it suggests comparing the physical properties ("weaponization") of the various anthrax samples. If it were a DNA comparison they were planning on doing, they wouldn't need to go back to AMI for more samples, since they've got the sequence from Florida already (the isolate from samples taken from Bob Stevens).
