No point on dwelling on this.
In the end, bar Graham Poll and Nemanja Vidic, Dowd has been universally condemned and ridiculed for his performance and that is far worse than any sanction the FA could impose IMO. In fact I wouldn't be surprised if the next few Villa matches he reff'd weren't a bit lopsided in our favour.
In the end though, the more we make noise about this then the more we just look like a small time club that can't accept we were beaten by the better team, regardless of the circumstances. Onwards and upwards.
