Yeah typically speaking what you shoot at will get hit. This is why gun safety is important, the people who unsafely shot directly at her are a hazard and shouldn't have guns. She's especially unlucky in the sense that she was struck in a sensitive area.

That being said, I've been rained on by birdshot and I've never had something like this happen to me. YMMV, but you couldn't have found a more freak accident scenario to present.
