Watch one man who was “almost a school shooter” tell his story

NBC's Katy Tur spoke with Aaron Stark, who penned an op-ed saying he was "almost a school shooter" when he was a teenager, but the lack of access to an assault rifle — among other things — stopped him. "A bigger issue was love. I had a severe lack of love, and I really think this kid did too," he wrote to 9News.

He told Tur on Tuesday this is about "more than just guns," and that "love is what we should focus on. Focus on communicating with the people who we think need it the most."
