You may want to read the article - they did call the police. Unfortunately it takes less time for someone to violently smash through a door than for the cops to arrive.
Interesting that you summize that they were apparently silent as this guy smashed their door
And, would you really play the odds that someone violently entering your house would suddenly have a moment of clarity when they entered? He was messed up enough to think shattering his own window was a viable option to get into his house.
