Presidential candidate Jeb Bush made an eyebrow-raising comment in the wake of the Oregon school massacre -- saying "stuff happens" in response to a discussion about gun violence. Bush called the shooting in Oregon "heartbreaking," and said he also had challenges that he faced during his tenure as governor of Florida. "Look stuff happens, there's always a crisis and the impulse is always to do something and it's not always the right thing to do," Bush said at the Conservative Leadership Project in Greenville, South Carolina, referring to taking away rights.
