Tasers kill, but do they actually save lives?

We've heard the catch phrase many times in the last few days, tasers are supposedly saving lives. Here are some recent examples:

London Free Press (November 21, 2007): Taser critics don't know what they're talking about, Fantino says
"“I can say without qualification that Tasers save lives,” said Fantino."

570News Victoria (November 19, 2007): Police weapons expert says Tasers save lives, prevent injuries
"A Victoria police weapons expert says Tasers save lives and he personally believes he would have killed several people in the line of duty if it wasn't for his Taser. Const. Mike Massine says his use of the Taser diffused several tense situations where using his firearm was the next alternative.

CBC (November 17, 2007): RCMP to review Taser policy in wake of airport death: commissioner
Numerous police forces say the weapon is a crucial "non-lethal" option for officers that helps save lives and protect both them and civilians from injury.

Not that there's any hard evidence of course, on the contrary, there's a growing number of cases in which the Taser has been considered a primary or secondary cause of death.

So how can "experts" keep claiming that tasers save lives?

They use a technique called informal predictions, which are often nothing more than opinions marketed as "evidence".

Here's one of Taser's own fallacies, from Taser's paper: TASER Device Liability and Litigation Riskown fallacies (p.3):

TASER technology is saving lives as well. Houston (TX) Police reported that in 39 instances between December 2004 and October 2006, incident involved officers would have been justified in using deadly force instead of stunning them;

Taser makes several mistakes in reasoning:
- reporting that in 39 instances officers were "justified in using deadly force" doesn't mean that these officers would have actually used deadly force if they wouldn't have had a taser.
- using deadly force doesn't guarantee that the "victim" will die from it. There are many ways to shoot someone without killing; try the legs for example. And not all "use of deadly force" will actually result in a hit; police officers miss too.

So how many lives were actually saved? We don't know and neither does Taser. There is simply no hard evidence. What we do know for sure is that tasers kill. There's proof that between June 2001 and June 2007, there were at least 245 cases of deaths of subjects soon after having been shocked using Tasers.

Then why are there so many police officers repeating the "tasers save lives" myth? Well, why don't you read it for yourself?

Note: Not a single journalist asked what the reasons are for believing that tasers save lives. Neither did anyone bother asking what the equation between lives saved and people killed is: so much for sound evidence or good journalism.
