As Gary R. Welsh writes, "Seriously, The FBI Devoted Massive Resources To Seize A 91-Year Old Man's Private Collection Of Artifacts?"
Rush County's Don Miller is, indeed, a collector of long-standing -- and his collection of pots, arrowheads, bones etc. is enormous.
But it hardly seems to warrant FBI overkill (when we can't even find all of Tim Durham's more contemporary assets).
Although this Indianapolis Observer is not a fan of Welsh's conspiracy theories, he does raise valid questions here: is there something else the Feds are looking for while using the artifacts as a smokescreen? Such as (he suggests) information on the space program of the former USSR -- a project in which Dr. Miller evidently was involved.
