No, I want to hold him accountable for not assessing the situation before shooting. Will he shoot me next if he "does not know what is going on"? Police work often involves operating in a fog of unknowing. You give the citizen the benefit of the doubt and presume he is innocent before being proved guilty. You don't "shoot first and answer questions later."
Ah. Lucky for you, Tennessee established a toll free number for busy-body outsiders to call in and complain about the way the good people of Tennessee choose to self-govern themselves there: 1-800-WHO-CARES.
