Hmmm. The article indicates a broken window, and further ‘medical and forensic evidence’. If the broken window was the point of access, it might indicate that a lot of the cuts sustained by the alleged intruder could be traced to the broken glass. That fact would change the entire scenario. It then becomes ‘much ado about nothing’.
Where. Is. The. Line?
That is entirely up to the courts, and the judge, to decide. This is Canada, where the Rule of Law and the decisions of the court still mean something.
But really, why be concerned about it? The chances of any Canadian ever coming close to the lie are in the vicinity of winning the lottery - one in tens of millions odds.
