If they own the air above the private ground what happens when they use a helicopter to access public ground?
Air rights only extend to certain heights in most jurisdictions, usually to align with the height that aircraft fly. A helicopter that flies at, say, 20 ft above private property is generally trespassing. At 2000 ft, it's probably in authorized flight lanes and thus not trespassing.
Eliminate qualified immunity and you'll eliminate cops who act like they are above the law.
