When a baby was left in a hot car, everyone convinced that there would be no happy ending. The police officers couldn't break open the front window in fear of harming the child, so they ended up breaking the back window. the problem is, the officers were too big to fit through the hole.
Maybe the most heartwarming thing that happened during the whole incident, was that the child who saved the baby was wearing a Batman outfit. It's almost as if he woke up and knew he was going to do something heroic that day, and dressed himself accordingly.
