"You're selling cigarettes with fiberglass and chemicals in them just to kill off the population," Gille said. "And you can't really accuse me of anything if you're doing that, you know?"

"I'm still sitting and grappling with the weight of realizing that it was kind of a life-or-death moment," said Julia Martell, who witnessed the stabbing, which wounded 11 people.
