ITA.Certainly a possibility. However, if she's anything like the college students in my classes, I find it unlikely. They usually try to avoid the library at all costs, preferring the internet's ease instead. I also hold the opinion that she's simply not bright enough to have thought ahead sufficiently to consider the possibility of things being traced, etc. Her pattern of behavior suggests a consistent lack of forethought when lying or committing any act.
I think KC probably reads (or pretends to read) in jail to disassociate from her surroundings. Beyond that, KC appears to be a troll the net/slug a movie in to kill time type of girl. I'm fairly confident she's not wading through War and Peace.
She's never shown signs of carefully evaluating the consequences of her behavior. Seen a few of her "hangin' with my peeps" snapshots?
