Yes. In fact, Inspector Sam Theocharis, who used to work with me at the Ontario Police College as a seconded instructor, called me and asked me to have a look at that article in which he was quoted.
But yes, indeed, version 14, which was the last taser disc for training sent out, still contains video footage that was filmed by Citytv in Toronto. A gentleman was in a park on a very icy, slippery day, and they believed he had a weapon. He had his hands in his pockets, and he was kind of catatonic in that he wasn't moving, wasn't reacting, and wasn't responding to the police. They used an armoured car and fired a taser through an opening in the side of the door and were able to strike the individual and put him down without having to deploy lethal force. So there's that one.
I know of another one in Toronto. A very tall man, who, looking at him from behind, appeared to be roughly my age--mid-40s, early 50s, sort of--had a knife. He wasn't a teenager. He was a mature adult. He had a knife, and he was not having a good day. He was suffering from a mental illness. The officers got close and deployed the taser, put him down on the ground, and were able to disarm him of the knife and use the conducted energy weapon in the way we would all like it used, and they didn't hurt him.
So there are videos that are actually part of training that show positive outcomes. But of course the bad ones are the ones we remember. The good ones are not so easily recalled, but there are some out there.
