In an episode that I am watching, a man was wrongly jailed for a crime that he did not commit. Most of the evidence came from his brother.
He was actually innocent of this crime but his brother did it because his brother had committed dreadful acts on women (yet again, surprise, surprise). Those cases were never solved.
But the point is that a person cannot be found guilty of a crime that he didnt commit just because he MAY have committed another offense.
