"If the Crown's account is true" is doing a lot of work here.It's a pretty clear Murder One, if the Crown's account is true. Cops ID-ed themselves multiple times and the accused struck the cop with the car 3x, finally crushing him.
What else were the cops supposed to do?..... On duty cops have to be protected.
I don't know how far along we are in the evidence, so maybe at this point we have good reason to believe it is.
But as anyone knows, the report by the cops about an incident are almost always false and spun to make it look like the cops are blameless. They count on people defaulting to "On duty cops have to be protected" and just accepting what the cops say.
