"Unfortunately?" I would think it's more helpful to prevent future tragedies that the suspect IS alive and in custody, rather than committing suicide by law enforcement. Any insights about this person's motives, state of mind, personal circumstances, etc., can help us understand why these continue to happen. CNN is saying the shooter is 14 years old. A CHILD doesn't JUST DECIDE to do this. We owe it to the victims' families and our own children to learn WHY they do it, so we can work to recognize and prevent it. Him/her being alive helps to do that.
