No, ISIS isn't the issue -- it's not caring about the consequences of doing things that could get our right to fly drones taken away. Part of that is flying where you shouldn't and part is playing dumb on the ability of even small drones to carry dangerous payloads. Drones are not permitted anywhere near a major sporting event and you do not have to be a rocket scientist to know why. A Phantom class drone dropping a grenade sized bomb on a stadium filled with people could kill dozens -- that spell it out for ya?
