FAST AND FURIOUS: Police Chief Killed With Gun “Lost” In ATF Tracking Program. “A high-powered rifle lost in the ATF’s Fast and Furious controversy was used to kill a Mexican police chief in the state of Jalisco earlier this year, according to internal Department of Justice records, suggesting that weapons from the failed gun-tracking operation have now made it into the hands of violent drug cartels deep inside Mexico.” I don’t think it was a “failed gun-tracking operation” at all.
