 Bradley Plattek was at the mall in Bethel Park getting out of the heat. He was at the Trump rally on Saturday and dove for cover when shooting began. He says it was over quickly. But afterwards it was kind of more scary because we're like, whoa, that actually just happened. I can't believe it. Plattek says he got another shock when he learned that the shooter was from Bethel Park, which he thinks of as a quiet, safe community. Quill Lawrence, NPR News, Bethel Park.
