Dear Rick Santorum: CPR is good for heart stoppage. Not good for victims of multiple AR-15 bullets, which typically impart 3 times the lethal energy upon impact than a 9mm handgun bullet. AR-15 bullets obliterate organs and cause so much bleeding that victims die very quickly. https://t.co/5E0HBUFT9b
