I don't understand what this has to do with airsoft.
People do drive by shootings with paintball guns frequently. People get killed and disabled by baseball bats all the time. I can't tell you how many thousands of windows have been broken by baseballs.
Hasn't had any effect on their sports, so why would someone using sporting goods outside their context affect our sport?
So someone robs a store with a fake gun that shoots pellets. So what. Nobody was actually in any real danger, and the only person at risk of serious bodily harm is the guy with the fake gun.
I can tell you I FOR SURE would rather be held up with an airsoft gun than a real gun.
So despite what retarded acts people perform with airsoft guns, the fact is they're using it outside it's intended purpose. They're not putting anyone at serious risk of injury outside of shooting someones eye. And they're being punished for it.
So I don't see why anyone would have their panties in a bunch over this.
