A bad day for premier league refs

It's rare for me to be critical of match officials but our premier league referees - especially Mike Jones and Roger East - did not cover themselves in glory today. Both are relatively new, especially East, but that's no excuse for poor decision making.

East's performance stood out as refereeing 1970s style. Violent challenges, including one two-footed foul that could have merited a red card, were ignored. One of the ignored challenges led to  dissent from a Stoke player, Shotton, and a rare yellow card. Shotton was sent off in the second half when an Aston Villa player appeared to dice. Shotton did not touch the Villa player, but found himself sent off for a second yellow.
In London, Mike Jones unfortunately got the three biggest decisions of the game wrong.
Most apparent was a dive by Arsenal's Santi Cazorla for which he should have received a yellow card. Instead he received a penalty. Later Per Mertesacker handled in his own penalty area. Instead Arsenal were awarded a free kick. Finally, Alex Oxlade-Chamberlain was indeed tripped in the penalty area, but play should have been stopped five seconds earlier when Oxlade pushed a West Brom defender to the ground.
Unusually, both managers, Steve Clark and Tony Pulis, retained their sangfroid while being critical.
For East, I suspect the message from his superiors will be that he has to enforce the laws of the game more firmly. For Jones, I'm hoping this is just a one-off.
Jones could and probably should have sent West Brom's defender Olsson off after the final whistle when the usual hand shake appeared to be abused. Olsson seemed to give Jones' hand a might squeeze that made the referee flinch. I do believe that's violent conduct towards a match official. I wonder if he included it in his match report.
