I'm not willing to exclude anyone or any group from the list of possible suspects--either from the sources of anthrax to whomever mailed the letters--and neither should the cops. It could be foreign terrorists, our own home-grown variety, a combination of the two, or a lone kook. At this point, with few clues, we simply don't know who did it or why. There are probable suspects, but without knowing anything more, why should one group or individual be excluded?
I agree 100%, my wise FRiend...MUD
