Agreed. So many people seem to have a need for knowledge about the shooter or are (as CNN quips) 'in search of answers.' There are no ****ing answers. People are dead and there will never be an answer that could make anyone feel any better about it - or prevent it in the future.
it's relatively normal and healthy for people to want to try and make sense of an horrific or disturbing event, to understand... it might not make anybody feel
happier about what happened, but having a clearer picture of exactly what was behind events coming to the conclusion that they did, and what is happening as we move forward and try to come to terms with events... that sort of understanding can be very helpful to people.
with information and understanding, they can try to accept and maybe even forgive a little easier, grieve a little more completely, there is less doubt and uncertainty, a little more security is felt as a result of communities coming together in difficult times, by people sharing their feelings, and having relatively reliable information means less creative conclusion-making happens, less stress exists from imagined or otherwise irrational fears playing on people's anxious minds.
knowledge and education can make a HUGE difference, too. you can predict the possibility of certain events happening pretty well, if you know the behaviours to look out for.
for example: severely depressed people who go on to commit suicide are frequently reported by friends and family-members as having seemed dramatically more upbeat and happy in the days leading to their death (because they've made a decision, they know it's going to be over- they feel strangely relieved)... they often undertake 'tying up loose ends' type behaviours like telling friends and family-members how much they mean to them, giving people gifts, giving away possessions, etc. this happens so frequently that it's been provided as 'red flag' information for friends and families utilising depressive support groups for some time now.
if a friend of mine had known about these behaviours and what they meant, she would have rung alarm bells prior to her friends suicide, and he might still be here today- his expression of real unhappiness might have been taken more seriously, he could have received real help, and he certainly wouldn't have been found dead in the way that he was, by the person he was. a different ending may have been similarly tragic, but it may not have been. positive change could have come about.
