I have a better idea. What if we dismantle the Tour Eiffel and use all this useles iron planks to fix bars in any of the windows of Paris. Would serve two purposes, parisiens would be safer against drones or muslims entering in your room at night and zero risk of somebody putting a bomb in the Tour Eiffel. Win-win situation!.

If we forget all about the legal issues, to fly an $4200 eagle trough a lawmower is a really silly idea and an useless method to stop a drone unless your goal is spending so many money from the french as you can, as fast as possible. Eagles can not carry drones of more than 3kg so they will still drop the bombs in a dangerous unpredictable trajectory. With a target big enough the difference between having an eagle or not could be a few hundred dollars more in damages (with eagle). I can understand the coolness of having a powerful eagle sitting in your fist and parade in front of a bunch of chicks, but this is either an hoax, or PR (most probably) or the boys had seen too many times the Hobbit.
