Frankly that video isn't sufficiently good enough for VAR purposes, so I'd be a bit worried if any referee was minded to reverse (or recommend reversing) the original decision on that evidence, whether it had been given or not. The screenshot shows the defender with one foot between Lawless's legs and the other stepping over his trailing leg, while the ball is yards away. At best it's a careless challenge that was never going to win the ball.
The Concord penalty shout isn't in the video and I'd be interested to see it again, although I was almost in line with it on the near side, so couldn't have been much closer without being on the pitch and probably had a better view than a camera from the back of the main stand anyway. My view at the time was that Jones pulled back from making a real challenge, realising he couldn't reach the ball, and the forward was looking to go down under any slight contact. I'd put that one in the category of "seen them given" but feel it would have been rather soft. The handball shout simply has to be given in my book. The guy jumps in front of the crosser with both feet off the ground and arms outstretched. He's presenting the widest possible barrier and blocks it with an arm. We probably tend to see what we want to see in these situations
