I live in a boarding house with thirty other down-on-their-luck men and I own one of the only laptop computers in the building.  On a typical day, I have multiple people sharing this IP on my computer throughout the day, including some folks with extensive criminal histories and/or severe mental illnesses.  But I wouldn't expect to be held liable for anything they do on my machine, now, that would be not fair.
