It's entirely legitimate to argue it was or wasn't a penalty, but folk should at least accept the ball did hit the hand and that's what the VAR team and ultimately the referee based the decision on.
Why was the arm there? Again, it's entirely legitimate to argue that it's a natural result of jumping and Trusty has forced it there or that it was a foul on Trusty. That's football folks.
