no wonder he shot himself, anyone would......

I beg to differ, two different sources.



Sorry you are wrong. You could have a hundred tasers at one time and it would still be only 50,000 volts. The voltage in this case would be in parrallel which means that it will always be the same voltage. It would need to be in series to increase the voltage. Take for instance a 12 volt car battery. This is made up of 6 X 2 volt cells joined together in series (one after the other) to make a total of 12 volts. Now join 2 batteries together with jump leads, Red to red and black to black. The voltage will still be 12 volts. Put a link from the red on one battery to the black on the other battery and you then have 24 volts.
Basic physics, simples.



its amps not volts that kill you, trust me, im an electrician

There are two tasers in common use by officers. The M26 was introduced in 1999, and the X26 was introduced in 2003. There are others, such as the XREP projectile, and the X3 released in 2009.

There are several ways to measure complex waveforms. The "2.1 mA" mentioned above is the Average. In general, electrical engineers do not use simple averages, even if rectified, because they most often provide a misleading number.

It's fair to state that Averages in this context are the mark of a newbie, or someone with something to hide. They're that misleading.

The most common method of measuring complex waveforms is something called RMS (root mean square). For example, the voltage in your house is probably 120 or 240 volts RMS. This concept is explained in first year EE courses. All reputable brand digital meters in common use by EEs provide the RMS function.

Both the M26 and X26 are about 150 to 160 mA when measured using RMS.

This 150+ mA range might raise eyebrows, because it's clearly a number that is well above the safe limits of around 30 mA.

Part of the safety claim made by the manufacturer is that the output waveform consists of very short pulses (100us) of high frequency (50kHz), and these two waveform characteristics provides an increased level of safety margin.

Problem is... the X26 waveform has a DC pulse after the arc phase. This DC pulse is low frequency (19 Hz) and continuous 100% duty cycle. So the X26 taser is clearly less safe than the older M26 (even the manufacturer's own expert confirmed this fact). I believe that their in-house experts forgot about Fourier transforms and neglected to account for this DC pulse. They continued to proclaim "short pulses" well past 2003.

So the real question being asked is: What's the Effective current?

By the effects, the taser's Effective current is well above "2.1 mA". The taser usually does much more than just a harmless tickle. As I said, "2.1 mA" is misleading. The implicit claim that the Effective is the Average is simply preposterous.

The Effective current is self-evidently well above the level of excruciating pain (way above and beyond). It's also obviously well above the level where muscle lock-up occurs (that's the whole point). And there's growing evidence that the effective current might be enough to sometimes affect the heart (this is the very next step on the scale, right next to muscle lock-up).

The manufacturer claims that the waveform has special (magical?) characteristics to ensure safety. This seems unlikely since the M26 and X26 waveforms are so different. And there's a newer X3 model that reportedly emits about 40% less charge than the X26. So that claim is falling apart for numerous reasons (inconsistent, obviously preposterous).

It's worth noting that the taser-associated death rate was much less than one per month up until 2003. Starting in 2003, strangely coincident with the introduction of the X26 taser, the taser "associated" death rate ramped up to about 7 per month and has been at about that rate ever since.

It's also worth noting that the taser, assuming it did kill, would leave no explicit postmortem clues. So some folks would be able to invoke alternate explanations such as "excited delirium" to explain the deaths. They could enforce this by means of lawsuits against coroners that dare to find the taser a cause of death.

The whole issue is extremely complicated and there's a lot of history.

But the claim that the taser current is "2.1 mA" is very very wrong.

That would be enough to make any man want to shoot himself.
I can't get my head around one bit though. This chap had shot 3 people, kolling one of them and he is holding a gun to his own head. Well I am OK so far. It would seem to me that in an attempt to stop him killing himself and/or another person, the police used a tazer on him. Well I am OK with that as well. Now the chap still manages to shoot himself and eventually he dies. Again I'm OK so far. Now why the f**k do the family want another post mortem? What do they expect it to show? Are they sugesting that maybe it was the use of the tazer that made the chap shoot himself and that he was, perhaps, about to give himself up?


I think the Family has got a whiff of Mega ££££££££....maybe they want to become dead rich.. :roll:

Why tazer him?? when all that was required was well aimed shot with a plastic bullet, that would have knocked him back into the river not giving him a chance of discharging his shot gun
They where used to good effect in NI by the army

So true....21,000 volts from a spark plug lead tickles....but 35 amps from a 12 Volt Battery Charger really make you sit up and take notice....

I seem to remember a few people being killed by "donk" rounds as well.

So some contributers from TDO were present when the suspect was tazered?

Some folks saw the suspect sitting there just at the point he was tazered?

Can you tell me where the shotgun was pointing, and what direction he was looking in, did he shoot himself then, or two minutes later? What shirt did he have on?

FFS.

GAZZA: I DON'T KNOW RAOUL MOAT, I WAS JUST DRUNK

29th September 2010

Paul Gascoigne has admitted he did not know killer gunman Raoul Moat after all.

The football legend turned up drunk at the scene of the fugitive’s stand-off with police, claiming to be his pal.

But Gazza, 43, who has been sober for three months, said: “Did I know him? No!

“I was sitting in the house and I was bored. Then I started having a few drinks and he just came on the headlines.

“I went: ‘Oh, I know him.’ But did I know him? No! I got some chicken, a fishing rod, a couple of cans and a blanket to keep him warm and got in a taxi. I remember being stopped by the police.

“I said: ‘I’m going to see me mate Moaty.’ The police were laughing their heads off.

He added: “I remember saying: ‘I know where he is,’ and they asked where and I said: ‘The helicopter light’s on him.’ They said: ‘Paul, that’s a star.'

Gazza, who is mulling over an offer to manage non-league Garforth Town FC, told an Irish chat show he was winning his battle to beat the booze.
