If religious people want to help right now, let them ask what they can do to be of service to people in pain.
People seem quick to claim to want to change things, but I’ll bet they’ll be next to nothing done to help the mentally ill. After the dust settles they’ll be some attempts to introduce legislation to control guns better and to curtail the rights of the mentally impaired. What I don’t believe will happen is that after decades of neglect that the government will make a serious attempt at improving mental health care.
