TOTALLY blows my mind that the Police would release THIS statement. Anywho, they did, and OFF it goes. They didn't even say what a 'cycle' is or even offer 'we are investigating a malfunction'. Mate, hand the guy a noose and get it over with....Jesus.
I find it hard to believe a 'year old' copper would would effectively torture someone to death for 28 'cycles' without intervention from others on the scene. TWENTY EIGHT....twitch your finger like you're pulling a trigger 28 times...
What is a 'cycle'. It seems a 'cycle' is a pull - charge - and release of the trigger. That could be a microsecond long and up to 3 days long...
How do Tasers work?:
When you pull the trigger of a Taser gun, a blast of compressed nitrogen launches its two barbed darts at 55 meters per second, less than a fifth the speed of a bullet from a typical pistol. Each projectile, which weighs 1.6 grams, has a 9-millimeter-long tip to penetrate clothing and the insulating outer layer of skin. Two whisper-thin wires trail behind for up to 9 meters, forming an electrical connection to the gun.
The X26--the model commonly used by police departments--delivers a peak voltage of 1200 V to the body. Once the barbs establish a circuit, the gun generates a series of 100-microsecond pulses at a rate of 19 per second. Each pulse carries 100 microcoulombs of charge, so the average current is 1.9 milliamperes. To force the muscles to contract without risking electrocution, the signal was designed to exploit the difference between heart muscle and skeletal muscle.
Skeletal muscle constitutes 40 percent of a typical person's mass and is responsible for making your biceps flex, your fingers type, and your eyelids wink. It's organized into bundles of single-cell fibers that stretch from tendons attached to your skeleton.
...opening nearby ion channels that are triggered by voltage instead of by acetylcholine. As a result, a wave of voltage rolls outward along the fiber toward both ends of the muscle, moving as fast as 5 meters per second. As the voltage pulse spreads, it kick-starts the molecular machinery that contracts the muscle fiber.
By directly jolting the motor nerves with electricity, a Taser can stimulate the muscle and get the same effect.
The force with which a skeletal muscle contracts depends on the frequency at which its nerve fires. The amount of contraction elicited is proportional to the stimulation rate, up to about 70 pulses per second. At that point, called tetanus, contractions can be dangerously strong. [...] The Taser, with its 19 pulses per second, operates far enough from the tetanus region so that the muscles contract continuously but without causing any major damage.
To see just how different skeletal and heart muscles are, let's look at what it takes to seriously upset a heart's rhythm. Basically, there are two ways: by using a relatively high average current, or by zapping it with a small number of extremely high-current pulses.
In terms of average current, the 1.9 mA mentioned earlier is about 1 percent of what's needed to cause the heart of the typical male to fibrillate. So the Taser's average current is far from the danger zone for healthy human hearts.
As far as single-pulse current goes, the Taser is again in the clear. The heart's chronaxie is about 3 milliseconds--that's 30 times as long as the chronaxie of skeletal muscle nerves and the pulse lengths of a Taser. The single-pulse current required to electrocute someone by directly pulsing the most sensitive part of the heartbeat using 3-ms pulses is about 3 A. Because a Taser's 100-ms pulses are such a small fraction of the heart's chronaxie, it would take significantly higher current--on the order of 90 A--to electrocute someone using a Taser.
In the United States, about 670 people die each year under police restraint, according to the U.S. Department of Justice's Bureau of Justice Statistics. These incidents include arrests and attempts to control an uncooperative person who needs medical assistance, as well as suicides after arrest. Studies have shown that stun guns were used during about 30 percent of in-custody deaths in the United States. Although Tasers were involved in a sizable fraction of these deaths, one should not leap to the conclusion that Tasers caused them. One study found that 100 percent of in-custody deaths involved the use of handcuffs, and one might apply the same faulty logic to argue against ”killer cuffs,” but that would, of course, be absurd. Medical examiners have cited Tasers as the primary cause of death in only four cases to date, and three of those were later thrown out of court.
I think we'll find out it wasn't the Taser itself that was responsible for the guy's death. Put 20 bucks on it...anyone?.
