Whilst I applaud your United-centric interpretation of it, I remember it as Evans both panicking and seeing red at the same time and he would have fully deserved his sending off.
Definitely my favourite piece of bad refereeing ever, and in the end Drogba stopped diving after that so it had the desired effect!

The Dan James incident is a funny one, I suspect he's been caught feigning injury and that Giggs has decided he'd rather admit that than have himself and his medical team hauled over the coals for letting a player who may have suffered head trauma continue.
