It should be law that social workers with milk and cookies must be dispatched to all calls, not alone or course, but they should be there, and they should be the ones communicating to settle things down. And I'm serious about the milk and cookies. They will need to have gluten free and vegan options on hand as well.
Cookies bring everyone together and help ease a tense situation. Milk returns us all to childhood, the nurting lifegiving liquid.
