Canadian condolences to the family of Tucson PD officer Henry Fung who died of an apparent heart attack on Tuesday this week, one day after he reportedly "volunteered" to take a taser jolt on Monday for "training" purposes.

The medical examiner must STRONGLY recommend that the taser(s) used on Henry Fung be measured for 'output variance'. As we have learned in Canada, not all tasers perform the same way. Many have tested way outside the safety allowables set by Taser International. The medical examiner (and all the doctors in the world) CANNOT rule out the taser until the shock from the weapon itself has been definitively ruled out. Proper measurement is required.

On CBS News last week, Taser International said that proving the taser did NOT play a role in a person's death is an UNPROVABLE supposition. There's your starting point. Click here: http://bit.ly/tT8iYq

It's notable that no one has reported the duration and number of stuns Officer Fung recieved. Usually when a citizen dies after being shocked by a Taser, he or she is blamed, because they had so-called "excited delirium", were on drugs or had a previous medical history (doesn't everyone have a previous medical history??).

Taser International has been warning about multiple and prolonged stuns only in recent years even though, at the beginning, they told police, policy-makers and the public that the taser was "safe to use on any assailant".

That is NOT what they're saying now. One must wonder if Officer Fung was given an opportunity to read the fine print of the latest Volunteer Waiver Taser International put out.

Read closely and it is ALL there: Tasers CAN CAUSE dangerous and deadly metabolic and cardiac changes. Several "suspects" have died MANY HOURS after taser shocks because of changes brought on by acidosis, which causes the muscles surrounding the heart to fail.

The city of Tucson cannot accept the "averages" Taser International spouts -- according to the original spec sheets, the true PEAK OUTPUT of Tasers varies between 151 and 162 milliamps, when "working properly". Any first year med student can tell you that shocks between 30 to 100 milliamps can KILL. Add to that, the invasive nature of a taser used in 'probe mode' - resistance under the skin is next to NIL.

And another shocking revelation: there are NO electrical safety standards for shocks UNDER the skin. Check with the Underwriters Laboratory, the IEC or Canadian Standards Association and you will quickly confirm this fact.

Taser International has some SERIOUS explaining to do. And you can be sure that their damage control machine is in full swing. I follow the company on TWITTER and they are a company which normally posts several TWEETS per day. They've been ominously silent since the day police officer Henry Fung died.

The Department of Justice ought to investigate how this technology was approved without enough rigorous science being applied.

One pig in 1996 and five dogs in 1999 and no true human trials until years after initial sales, should be alarming to all citizens.
