Three weeks after the Parkland high school shooting, Gov. Rick Scott has a gun-control bill on his desk that challenges the National Rifle Association but falls short of what the Republican and survivors of the massacre demanded. Now he must decide whether to sign it. Scott has not said what he will do, and he plans to take up the issue today with relatives of 17 people slain in the attack. He has two weeks to sign it, veto it or let it become law without his signature. The measure would, among other things, up the minimum age to buy rifles, extend a 3-day waiting period to include long guns, and allow school employees to carry guns in school if they go through law enforcement training.
