As the author well knows, sexual assault in Canada is not just rape.  It is defined as "sexual contact with another person without that other person's consent."  In the broadest sense it could include as little as an unwelcome kiss in a bar or as much as outright rape.  I think we would all expect the criminal conviction rate on minor unwanted sexual assaults - which are far more common than rape - to be next to zero.  So throwing out alarmist garbage statistics like only 3 out of 1000 sexual assaults result in conviction when the real discussion is about rape is irresponsible and exposes the author to be nothing more than a politically-minded activist and opportunist.  

The goal here should be to find justice - for the victim, for the accused, and for society.  Measuring conviction rates against some sort of contrived scale completely misses the point.
