Assumptions that can kill hundreds of people. Its illegal to point a laser pointer at an airplane worrying that it would blind pilots even though most planes are on autopilot. At the same time they don't consider to assume that Russian backed rebels would have missiles capable of shooting down planes.
I hope they stay away from Israel/Gaza airspace as well and not wait for another incident. Maybe airlines should publish their flight paths to the public so that we can make our own decision!
