G20 Demo: Not too much trouble for photographers... this time

Apart from being caught up for hours at the demonstration, photographers and others associated with the press seem to have carried out their jobs succesfully, without too much interference from the police.
However some were treated disrespectfully. One of them described to me how he was abused.
He said:  "As usual, I had a lot of trouble. The police pushed me and I even got hit."
He added:  "I tried to defend myself but I continued being pushed. It does tend to happen when everybody gets a bit nervous."
But it is not all bad news. Most photographers were able to do their job without too many distractions.
