It's ridiculous to suggest that we should do nothing about an injustice that comes to our attention just because it's not the only injustice in the world, and we're not going to do anything about most of them (not least because we don't know about them). Some injustices we care more about than others, and we need not justify ourselves to you. That said, if you see a news story about a 12-year-old expelled because his mother packed him a steak knife, feel free to submit it. I can't promise it will be upvoted onto the front page, but it's worth a try. I will probably read it if I notice it. Not to justify myself, but to satisfy your curiosity, I will attempt to answer your question. This girl's situation attracts attention here on HN, I surmise, because her intent was scientific in nature. Okay, it's a teenager's science experiment, but still, she was exploring the physical world. This is something that a lot of people here can relate to.
