The bottom line is your husband doesn’t HAVE to call the police. He does so because they gross him out. He does so because they inconvenience the image he or his business is trying to portray.
There are very few situations when anyone HAS to call the police. Being inconvenienced or grossed out by the needy is definately not one of them.
“Come, you that are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world; for I was hungry and you gave me food, I was thirsty and you gave me something to drink, I was a stranger and you welcomed me, I was naked and you gave me clothing, I was sick and you took care of me, I was in prison and you visited me.’”
