We can all impact culture.

The news out of Newtown is once again a punch in the gut and heart. Adam Lanzas mother planned on giving her son money for a shiny new gun for Christmas, had he not chosen to annihilate her, 20 innocent children and 6 educators on December 14th. What in Gods name made her think that guns were a good choice for her emotionally disturbed son? We all did. The friend who didnt tell her strongly enough that mental illness and guns are a bad combination. The communitys gun owners who knew the Lanzas. The culture we all helped to create that let her think this was OK. Gun organizations and politicians are fond of saying they have to do something about mental health, but rarely use the term I in connection with this responsibility. It is not ethically credible to insist on a lack of government regulation, but then shirk the responsibility of self-regulation. We are all morally responsible for the guns we purchase, and the subsequent people we give our guns to; as well as the people in our houses where our guns are kept.
