They would rant and rave and likely press charges if you jumped out from behind a bush and yelled BOO even though they had never been assaulted in any manner either before, during, or after their scare yet they cannot understand that one who has been shot at or seen others shot at or blown up under circumstances similar to what they find themselves in probably will react quickly and violently.
