Citizens, police, prosecutors, judges, and juries, among others, must use a "reasonable and prudent person" test to determine whether or not a use of deadly force is contrary to or permitted by law. Because reasonableness reflects a consensus among members of society, then if society's opinions change, the application of the law can also change. Likewise, if the consensus about what is reasonable differs between two jurisdictions, then the application of the same law in those jurisdictions can also be different. Obviously, certain inviolate standards limit drift and differences. But even these change once in a while (Civil Rights Act of 1964, Heller, McDonald, Terry, castle doctrine laws anyone?). I'm curious to know if you believe that widespread access to videos of violent crimes, self-defense shootings, and police use of force might lead to changes in society's consensus regarding reasonable use of force. 1) Has your opinion of what is reasonable use of force changed as you've watched these videos? 2) Do you believe that other members of society are also watching these recordings, and that their perceptions of what is reasonable are also changing? 3) Do you think that easy access to videos from all over the country is likely to reduce variation between jurisdictions regarding reasonable use of force? Please don't allow this thread to stray into criticism of police actions. There are lessons that citizens can learn regarding use of force from videos of officer-involved shootings, but that's probably about as far as it should go.
