(AP) — Gun maker Remington has moved a lawsuit filed against it by families of those shot in the Sandy Hook school massacre from state to federal court, where at least one expert says it has less chance of succeeding. A 2005 federal law shields gun manufacturers from most lawsuits over criminal use of their products, but it does include an exception for cases where companies should know a weapon is likely to be used in a way that risks injury to others. In addition to Remington Arms, which makes the rifle, the defendants are Camfour, a firearm distributor, and Riverview Gun Sales, the now-closed East Windsor store where the gunman's mother purchased the Bushmaster rifle in 2010.
