Don't recall where I first saw this; may have been Drudge. The main link went to Infowars, which is extremely antigovernment biased. Subsequent searches led to a couple of other sources; but most referred back to the Infowars article. Can anyone find an un-biased source (or, at least one less biased than Infowars) to confirm this story? And if it's true, why would the USPS, even with its investigative branch (USPIS) need a couple of dump truck loads of ammo?
