Comfortably traceable.

And since most libraries now require internet access tied to either your account, or MAC address logged, this was stupid of her.

Helpful advice: use someone else's wifi (change your MAC address and don't transfer any personable information as well) in a state outside of your own, and through an anon proxy, then erase the wifi logs (if any, most consumer wifi don't log very well) when she's done. The FBI would normally work on interstate crime like this, but it's so small fry that they'll ignore it unless the media gets involved.

She made up for it with the costume, I think. That threw me off.
