Why do you blame someone that was not even around for a mass shooting. Blame the shooter, yes the only blame. Do not blame the gun, it was loaded by a person, the trigger was pulled by a person, the same that held the gun during the shooting. Does he/she have mental issues? Is he/she a hater? Has he/she showed any possible intent before the action? It does not matter the answers if attention was not enough to stop the action before then it is a full crime. It is sad either way and I, as so many others, pray that such waste of life and cruel events never happen again.
