No, not at all. When police officers appear at the scene of a crime, they must assess the risk. They respond, based on this assessment, with the tools at their disposal. And they don't always use conductive energy weapons. Sometimes they use self-defence techniques, and sometimes they use pepper spray. And if that doesn't work, they use the nightstick. And when it doesn't work, they use conductive energy weapons. Once again, you need to understand that conductive energy weapons enable you to control the client, when they work. Shortly after deployment, the fight ends and the client is handcuffed.
There have been incidents, not only in Canada but elsewhere in the world. A client did have a heart attack once afterwards. But what was the heart attack due to? To date, according to reports and based on an assessment of the various situations, the conductive energy weapon, when used, has not been associated with the onset of a heart attack.
