(NBC NEWS) Ten families touched by the Newtown massacre filed a wrongful death lawsuit Monday against companies that made, distributed and sold the Bushmaster AR-15 rifle that Adam Lanza used to kill 20 children and six staffers at Sandy Hook Elementary two years ago. The suit argues that the gun is a military assault weapon that never should have been on the general market.

"For far too long the gun industry has been given legislative safe harbor from this standard business practice. These companies assume no responsibility for marketing and selling a product to the general population who are not trained to use it nor even understand the power of it."
