I was trying to figure out what a "misdemeanor sex offender" was (what most people think of when they see "sex offender" is felony-type offenders), and from what I was able to figure out, that's along the lines of people picked up for soliciting prostitutes or indecent exposure. Yes, that's a problem, but so is not having access to books -- the latter has as many, if not more, ramifications than the first. (Heck, the two are occasionally related -- the 5th floor of our university library was notorious for people who exposed themselves there.)
