I know a guy who collects human skulls. They're not hard to legally obtain. I don't know why the fact that she was carrying it was a big deal. I mean, the skull could be the remnants of a crime, but so could a hundred things in anyone's luggage. A skull is just a curiosity for people who don't get out. You can buy skulls on ebay, folks.
Man, I should take note of that. Maybe next time my friends and I are bored, we'll call and thank customer service instead of leaving random people voicemails about their membership in the Socialist Party of America... XD
It's actually a pretty neat website.
