Seems to me that if you tune into a TV program that advertises players bashing into each other for 80 minutes then you're likely to see the odd dislocated finger or smashed face being attended to.
One requirement of the TV broadcaster is to as close to the action as possible and make the viewer feel like they in the thick of it. I'm sure there were a fair portion of the crowd who saw the blood and staples. The camera was johnny-on-the-spot imo.
I'd like to know how many complaints the ARL and Channel 9 recieved - I bet its bugger-all.
The majority don't mind a bit sideline surgery at all... as our authoritive TFR poll shows.
