The murder charge may have been a bridge too far. But, you need to consider this man knew his child had issues and had threatened to "Shoot up" his school. The FBI had even showed up at his house. The guns should have been under lock and key and probably not even on the premise. The father should be held accountable in one form or another. The FBI dropped the ball on this too. It isn't the first time they have been irresponsible in handling advance warnings about a school shooter. Talk about accountability, they should have been faced serious consequences in the Parkland shooting and, now, in this one.
