"US forces have captured over a hundred of the HS50s from the Iranian police shipment. That amounts to over 12% of the total number of rifles imported by Iran to fight drug dealers, a dodge that has grown more threadbare ever since the invasion of Iraq. The Iranians have not claimed -- yet -- that they managed to lose one-eighth of all the new rifles intended for their police, and the Iranian government was clearly the recipient of the arms. In fact, Austria defended the sale on that very point.
Pardon the pun, but this is literally the smoking gun. We can trace these weapons from its manufacturer directly to the Iranian government. The quantity in which they have been found in insurgent bases precludes any explanation that a few just got mislaid; they obviously have been transferred from an Iranian state organization to the terrorists in Iraq. It's the clearest evidence of Iranian involvement in attacks on Americans. The involvement of the mullahcracy is undeniable, and it is a direct retort to those who keep claiming that Iran has no stake in Iraqi instability."
