The problem with tasers is that you don't know whether the victim will survive an electrical shock of that many Joules. It only requires a tap on the button to send a shock that can interrupt a heartbeat, but cops almost ALWAYS shoot tasers for ten seconds at a time and do this multiple times.
Take this example, where cops shocked a 54-year old twice, once for five seconds and then again for a whopping 57 SECONDS.
What they're doing is basically operating a defibrillator without any knowledge of their patients' health.
I found a handy summary of the energy involved. Keep in mind that I haven't taken chemistry or physics in nine years:
1. Watts are the expression of electrical power in a device. watts = voltage x amps (w = v * a)
2. a) Electrical output of defibrillators is expressed in terms of energy
b) Joules (J) or watt-seconds (Ws) describe the power (watts) and the length of time it is applied (sec)
c) Thus Energy (Joules) = power (watts) x duration (seconds)
According to
a study of defibrillators that talked about improvements of the devices in the early 1960s when they became efficient at saving lives:
A typical taser emits something like 0.00015-0.0021 amps at 50,000 volts. Let's take the low end of that and see what we get.
0.0015a * 50,000v = 75 watts
What a light bulb gets. Sounds harmless, right? Wrong. That's the power emitted
per second. Defibrillators, while emitting a higher wattage, only do so for a fraction of a second. As in 0.0025 seconds. That's impossible wth a taser gun. The cop is going to hold the trigger down long enough to let the probes hit his target, and it will take at least two seconds to make sure it has hit and has shocked the target from the time the cop pulled the trigger until the time the cop releases it.
power (watts) x duration (seconds) = Energy (Joules)
75 watts * 2 seconds = 150 Joules
75 watts * 5 seconds = 375 Joules
75 watts * 57 seconds = 4275 Joules
The hospital can use defibrillators at a setting as low as 20 Joules to interrupt heart rhythm. Now, I understand that the shock is spread out over however many heartbeats occur in the given shock period, but the fact remains that that a LOT of energy introduced into a human being that shouldn't be there. Many people have irregular heart rhythms and/or underlying ailments that can kill them if they are shocked. That's why my dad carries around an ECG reading of his heart rhythm when he goes to the hospital -- he's run marathons for so long that he has a runner's heartbeat, and it's vital that doctors know this whenever he receives any kind of treatment; overlooking an irregular ECG can kill someone.
So yes, I'd rather have a cop wrestle me to the pavement (not that I would ever be stupid enough to fight a cop). We just don't know the full implications of shocking a person several times in under a minute at high voltage.
Agreed. The sane ones can repeat the Ben Franklin quote (summary: those whose sacrifice liberty in exchange for security deserve neither) until they're blue in the face, but sheeple don't listen to reason. They don't care about being in pens or eating moldy grass; it's all about the wolves. Of course, sheeple don't realize that a good shepherd knows how to kill wolves AND let them graze the fields.
