The paper reports on an incident from last December at an LA library. As kids waited in line to check out books, one patron watched pornography on a computer within sight. An uproar ensued, but city officials say the First Amendment grants patrons a right to access most porn on public computers.
Technically, libraries can install porn filters, but they must remove them if a patron asks for a site to be unblocked. Some cash-strapped libraries, unfortunately, can't afford the blocking software, so they've taken a low-tech approach: isolating computers so bystanders can't see the screens. I hope they don't give library porn watchers too much privacy, though!
