Yes, but what about "out" heroes such as Iron Man, Wonder Man, Black Panther, Wasp, FF?
As for what about heroes might be sued for- how about unnecessary force, reckless endangerment, unlawful trespass( how many times have we seen Spidey, DD or Wolverine enter a private dwelling without explicit permission of the resident- were they police or FBI/DEA agents anything they found would be excluded as "fruits of the poisonous tree"( illegal search and seizure), property damage and divers issues!

As for Nighthawk- isn't he dead?
