I do not see where this insane shooter is political biased one way or the other...

Not every insane shooter is motivated by politics...

This person hated everyone equally and has left numerous posts and videos of his long held hatred.

Someone (family, friend etc) should have alerted law enforcement of his insane threats and post long ago...

My heart goes out tho the children and their loved ones who are affected by this senless killing of innocent children.
