NeeNaw - can I suggest you get your facts right. The job from police was "Male on floor knocked out" and the crew did NOT jump in without waiting for police. They are a very experienced crew and know better than that. They were attempting to treat the patient, when the suspect came up to them. He was smartly dressed and they had no way of knowing that he was responsible for the patients condition. The police had given no indication that the situation was dangerous.
