This is such a horrific tragedy! To think that all the endeavors to assure society doesn't allow weapons into the wrong hands is a complete failure. Only God knows what goes through an insane man or woman's mind before they commit atrocities. There is no prevention to stop them or predict who the insane are or when they become insane to do such a horrible attack on innocent people. 

It does not matter if this monster murdered police, women, men, or children. But, what matters is he murdered his fellow Americans for no cause or justification whatsoever. 

My heart goes out to the families and pray to God that if there are any others involved that they are removed from society forever. There is no place for crimes that have no cause, no conscience, no mercy and no reason.
