As someone who owns, flies, and uses multi-rotor flight systems (none of mine are autonomous so it annoys me to call them drones, especially when I have worked on autonomous ones), don't be the (generic - not one person here) d!ck that goes and destroys someones multi-thousand dollar piece of equipment because it annoys you.
If they are flying illegally? Fine, deal with it properly.
If not flying illegally? Talk to them. See if an agreement can be reached.
I guarantee you won't come to a peaceful and reasonable solution if you go the vandalism route...
