It is interesting to see perjury charges brought against the RCMP officers who were seen  by numerous witnesses and caught on video Tasering to death an unarmed immigrant at a Vancouver airport. No charges relating to the obviously excessive use of force are being laid; only charges of lying under oath during subsequent investigations of their criminal conduct. This is in line with recent American practice where high profile defendants such as Martha Stewart and Barry Bonds were never charged with the substantive wrongdoing but were convicted of lying when they denied their alleged conduct.
