If he had mommy issues I can understand him wanting to takeout mom but strangers kids? Even if he was abused why shoot those kids which is ABUSING them. I thought most child abuse victims don't want to see that happen to other kids.Only two words that I can say that best describes the shooter in my book right now...cowardly scum.
I'm sure that others can think of something even more to call him but that's just how I feel about him.
Remember this is CHILD ABUSER/mass murderer Adam Lanza and not 'the gunman or shooter'.
