Witnesses perceive events differently

R. v. Wilcox, 2014 BCCA 65:

[28]        I do not quarrel with the proposition, stated in Burd, that when a number of people observe the same event, they may see or recall the event differently. Such discrepancies do not reflect a witness' credibility, "but simply [show] the difficulties and frailties of eye-witness evidence" (at para. 23). I am not convinced that this principle applies in these circumstances.
