I mean that video shows four referees all agreeing that he's handled the ball deliberately. They felt in real time and on replay that it was an intentional playing of the ball and as such he can't use his arm, period.
I know we all disagree, but that's all there really is to it. And yes there will be other similar decisions where the referees decide it wasn't deliberate and yes you know which clubs will benefit from those. But it is probably time to move on.
And also stop playing Tarkowski because he's going to do this nonsense again.
