They would have unassailable experts on their staff that would know about the difference between average and RMS current, and they would know the applicable safety standards. They would be able to provide expert and unbiased advice to the SECU committee regarding the purported safety margin (remember Smith's evidence: "15 to 1" safety margin?) of the various taser devices (M26 and X26).
The CSA experts could look at the specification sheets, and could even comment on the changes to those spec sheets over time (RMS current value expunged, why?).
I see no downside to the CSA being asked to get involved at this point. To ensure that you receive a consensus opinion, invite not just one expert, but two or three of their experts. They should all agree. This should settle the argument about safety once and for all (provided that they do not overlook any real information hidden under a layer of Taser smoke and mirrors).
At the outset, all that is required is a documentation review (pretty quick). Just compare the specified current values ("average" and RMS) to the applicable safety standards in Canada. Actual equipment testing can follow later if required.
By the way, keep Taser out it it for now. Just get CSA's unbiased opinion based on present electric safety standards and compare those to the taser spec sheets (including RMS current values). DO NOT ALLOW TASER TO INFLUENCE THIS EVIDENCE. Ask the CSA experts if they have had any contact from Taser or similar taser proponents, or if they have ever had any relationship to the taser controversy.
As a starting point, here is a graph that Taser's Kroll included in his IEEE Spectrum article. I've added the red information regarding the X26 taser's RMS current ("151 mA RMS" from the early X26 specification sheet, expunged in later revisions, rarely mentioned) and primary frequency component (just 19 Hz).
