(AP Photo/Richard Hartog) (Newser) – Federal authorities have arrested three ex-Marines accused of selling assault weapons to Los Angeles gangs. The trio were arrested, along two other people, after the alleged ringleader sold two crates of weapons to a federal informant he believed was a gang member, authorities say. Police sources tell the Los Angeles Times that more arrests may be made in the case. A Navy SEAL was arrested last week for allegedly selling guns that he had smuggled into the US from Iraq and Afghanistan. Click here for that story.
