Father Of Oregon Mass Murderer Blames Guns For School Tragedy [VIDEO] Following the Oregon Massacre, the father of Chris Harper-Mercer has stood firm in his belief that he blames guns and his son for what took place at Umpqua Community College. Im not trying to say that theyre to blame for what happened, he claimed. But if Chris had not been able to get hold of 13 guns, it wouldnt have happened. In an interview with CNN, Mercers father spent most of the interviewing contradicting himself. Thats what guns are, he concluded. The killers. Its as simple as that. Watch the video below and tell us what you think. Is this disgusting? Is Ian Mercer blinded by denial?
