If the cameras are streaming back video that would be a very easy legal case against the person shooting. I'm guessing after it happens a few times and people see the repercussions they would stop.
US v. Causby is the only ruling I could find (that was 83 ft).https://supreme.justia.com/cases/federal/us/328/256/
I doubt it. I think it's more likely that they'll do the shooting from cover so they can't be seen by the drone.
