Make the movie about the victims.
‘Make a movie about the victims” I think that is frankly the best idea on this I’ve heard so far. Each victim, and their relatives, and their neighbors, and their doctors, their priests, their mechanics’ their masseuse, babysitter, first grade teacher, first employer out of the home, last ex-wife. Most folks have lives touched closely by other people. All these people are now reacting to what has happened to the person they used to know. What was Before has become After.
