I think the taser is being used as a cattle prod. It is used to gain compliance when a simple discussion would likely suffice.

In the case of the Vancouver airport incident, it wasn't even just the taser, rather it was a series of mistakes and errors in judgment that resulted in tragedy.

For example:
There may or may not have been a polish speaker in the vicinity. Why did the cops not use him, if available?

When you have four male cops surrounding a jet-lagged, disoriented person, why the need for the taser?

After he was tasered, why not let emergency personnel treat the victim?

Finally, at the hearing, the police have supposedly been contradictory of each others testimony.

Of course, not wanting to get sued, these observations are based on what I heard on the news. I was not at the hearing.
