Yeah it is beyond belief. Did a quick search, most articles are just the exact same limited info. Although one says the driver claims he was able to prevent the guy from taking his pistol and stopped the bus and both got off to continue fighting - why the fck didn't he use it to shoot as the guy was getting back on the bus ?/., and presumably if the other armed guard used the back egress and only had a shotgun perhaps he couldn't have blasted without hitting both but how the fck does he then let the guy quit fighting the driver and get back on the fcking bus without stopping him dead?/. Its a whole lot of WTF. I suspect it's also a whole lot of diversity failure
