FindLaw columnist and Rutgers law professor Sherry Colb discusses whether there is any way, through the legal system, to address parents' concerns about Jack McClellan, who blogs about his sexual interest in little girls and calls readers' attention to places where large numbers of children can be found. Parents have fought back by attempting to track McClellan's whereabouts, but can more be done without violating the Constitution? Colb surveys the legal terrain, and notes that, in fact, if McClellan's blog is properly categorized as a map for child molesters, legal remedies may indeed be available.
