Using drones wasn't going to dramatically increase the damage someone like the Boston Marathon bomber did or decrease his chances of getting caught. Would be domestic terrorists are deterred by the fact that they are domestic and will eventually be arrested given the dragnet of internet and CCTV surveillance we all live under, not because they can't somehow fly a bomb into a stadium instead of leaving a pressure cooker backpack. Drone availability is way down on the list of things a normal person would consider before deciding to pick up domestic terrorism. Top of that list is probably whether they can win a shootout with the police force when a dozen swat vans inevitably show up at their address.
