Sen Bill Nelson D-FL spoke of "needed legislation" within minutes of the shooting.
It appears now that the killer had a legally checked firearm in his luggage and flew in from Alaska. Upon landing, he retrieved the weapon and loaded it while in a restroom, then emerged and began firing.
There will be a push now to ban firearms from checked baggage completely! This would be a game changer for shooters travelling to events or hunting trips via the airlines!
