It takes the average PD unit close to 8 mins to get on scene, another 3-5 to make contact with complainant. It takes EMS/Fire an average of 10 mins to get on scene and about 5-8 for PT contact. This does not included the delay from you dialing 911 to the unit getting dispatched. It takes the human body anywhere from 15 seconds to 6 mins to bleed out from a wound. As danny said I do not trust any one in the world except close friends, my wife and my partner on the ambulance. Other than that everyone else can fuck off.
