Mr. Turnbull, the owner of a self-serve laundromat, had warned Mr. Molson, a known heavy drinker, to stay away from the premises. Later, Mr. Turnbull found Mr. Molson doing his laundry. He ran to within a metre of the startled Molson, raised his arm and shouted, "if you are not out of here with those rags in one minute, I'll break both of your legs." Mr. Molson began to comply, but suddenly fell to the floor suffering a heart attack. After recovering, Mr. Molson sued Mr. Turnbull for 'assault'. Who will win the case and explain your reasons why
