I suspect the minimized version, "Why would she do that?" would have been well received. I don't think anyone understands why the "I'm not from the US" clause is there and I personally assigned a reasonable probability that it was a short-hand stand-in for the following sentiment : "The US has so much gun violence that they must have some kind of expertise that leads them to know that its a good idea to save skull fragments in case the doctors need them. Lol, just kidding, that was sarcasm; I just wanted to bash the US for their high rate of gun violence." Of course I accept that this may be mis-interpreting it. The only other meaning I can parse is: "I imagine that everyone in the USA learned about this event in great detail in their school lessons/etc. I haven't so....could someone explain why she grabbed the skull fragment?"
