are you suggesting that shooting guns at planes should have been entirely legal until a "measurement study" were run that could confirm in fact that harm could be done? E.g. to prove that the bullet could in fact pierce the window of a plane 20 feet off the ground and kill a passenger, for example. Well we haven't tried yet, how can we know such harm is even possible? Or how likely is it that shooting a gun at a plane will actually kill one of the passengers in the plane, or blow out the engine and cause a crash, perhaps it's just so rare? Therefore it should be legal! Else repression! seriously?
