The former president of Blackwater Worldwide and four other former officials at the embattled security firm were indicted Friday on federal weapons charges, partially the result of a raid two years ago by agents that rounded up 22 weapons, including AK-47s. The indictment issued Friday charges Gary Jackson, who left the company last year in a management shakeup, along with four other former workers. The charges against Jackson include a conspiracy to violate firearms laws, false statements and possession of an unregistered firearm.
