Understood, but to date, common law has not protected anyone who has destroyed a drone and statutory law resulted in them arrested and liable for damages. You may like your chances, and being a lawyer yourself, you may be able to prevail, but for most of the people who are doing the chest-thumping about smashing drones out of the air, it would cost them plenty whether they were to win or lose, and their chances aren't going to be as good. It's a risk I personally would not take.
