No.
I see Grey's feet secure on the ground, and movement consistent with striking something to her left. Nothing to suggest she was wrongfooted at any point. Mrs Ward was more vulnerable, being between her and the road. I see movement consistent with a push and then Mrs Ward falling into the road.
But what does it matter what I saw? William Walker was actually there and saw the whole thing. The judge found him to be a reliable witness and the footage is consistent with his account.
Grey knew cyclists used the path. She wasn't in fear and she wasn't acting in panic or self defence. She was the aggressor and she assaulted Mrs Ward. CCTV footage and at least one independent witness show that they were stationary and she struck at Mrs Ward, which caused her to fall into the road.
And actually, sentencing guidelines start at one year longer than Grey has been sentenced to serve. She's had mitigating factors taken into account.
If there has been anything untoward in the proceedings, I am sure you can trust Miranda Moore KC who, in addition to being an illustrious barrister, has the advantage of knowing everything that went on in court, to know about it and take appropriate action.
