When you throw a rock at a pack of wild dogs, how
do you know which one you hit? It’s the one that’s yelping. That

interest groups that are complaining — and by the intensity of
their yelps. Steven Greenhut says this is exactly the case in the
battle between charter schools and public teachers’ unions.
