As everyone knows, real life situations are very different from controlled situations. The program “Enquête” reported that testing on RCMP members had been suspended because of the high risk they faced. Last week, when I spoke to RCMP officials, I was told that testing had resumed, but in a controlled manner, that is officers were monitored and the tasers were not aimed at any body joints. That's not how things happen in real life. Furthermore, most police officers are in good physical condition.
The fact that we cannot conduct tests on people who may have ingested some illegal substances makes the results even harder to interpret. We cannot ask people to ingest illegal substances just to get them to react in a particular way.
Do the studies that you have confirm my assumptions?
