Will Liberals now call for 'Knife Control' with Ohio Dark Night Copycat?

Gun kills people, and so do knives, and this copycat had plenty, so why don't liberals call for knife control?

From The New York Daily News:

Scott Smith, of North Ridgeville, had a beige satchel that raised suspicion when he entered the theater. After Smith took a seat, an off-duty Westlake police officer who was providing security to the movie theater asked to search the bag.

The officer found a loaded 9mm Glock handgun, multiple loaded magazines and three knives inside, Westlake Police Lt. Ray Arcuri said. An additional knife was found underneath his clothes.
