There's no fucking way that no one noticed. At least one person had to. I ride a public bus and the El all the time with an iPod on, and I would fucking notice a rape happening if it were right beside or front of or behind me. I know they're kids, but my God, has no one instilled some kind of decency in them?
It's really scary that you can be in such a public place and stuff like this can happen. It almost makes it seem like all your standard safety rules are bs and that you're really not safe anywhere.
Besides commenting on the passengers, how brazen would a kid have to be to do that on a school bus? Part of me wonders if this was a popular kid, which is why no one would say anything, as fucked up as it is
