Look, you say the taser is not risk free. Obviously you admit there are risks. And so does the U.S. Department of Defense, which actually concluded in 2004 that it didn't want its military personnel to be tasered during training because, they said, there are risks. So they know what you know, but you are not prepared to actually admit, in simple layperson's language, that those 270 persons might have been alive today if they had not been tasered.
