It would seem an investigation would of been automatic if it was military grade anthrax, like in high profile automatic at a Federal level..
I dunno. The ol Arkansas mafia had a way of hiding things, making uncomfortable things disappear into thin air. Just check the clinton death list from those good ol klinton arkansas days (when he wasn't raping Juanita or pardoning drug dealer Dan lasater, etc) and ponder how MANY PEOPLE died via suicide or plane crash with a few train track deaths and suspicious drive by shootings thrown in for good measure. Even the tainted blood rebates have a stinky connection that has warranted a full blown federal investigation FOR YEARS. For some reason, our federal government has been content to skim the surface of bill clinton's filthy behavior....what is festering under all the slaps on the wrist (ie his temporary suspension of the right to practice law) is a crawling mass of felonious behavior.
