I think they came because the wife sounded really upset on the phone. Police do just like to turn up to things though.

Here in Australia I called emergency services one time because a woman locked her kid and her keys in her car and the police were the first to turn up. They couldn’t do anything so they just stood around until the fire brigade arrived who were the ones that could actually pick the lock to the car. It just makes you wonder why the police bothered at all.
