Don't just do something! Stand there!
There are already penalties in place for anyone who disrupts or endangers air operations. No special case should be needed if they use a drone to do it with.
In the event that Something Bad™ happens, there will be cries from the voting public for politicians to Do Something™. As politicians have only one tool with which to Do Something™ (i.e. they can legislate), they use that and claim to Do Something™ even if it is completely redundant or utterly fails to address Something Bad™. If Something Bad™ continues, they will pass increasingly tough and thorough measures aimed in its general direction, being careful to note that any failure to alleviate the issue is simply an indicator its severity. In fact, it is beneficial to said pols that Something Bad™ be nebulous enough that it can be defined as an ongoing war, something that never goes away, thus providing them many election cycles where they can repeatedly Do Something™. That's the way to do it!
