Lincoln Gotovac, 26, took Casino Canberra to the ACT Supreme Court over the manhandling he received from security guards during a night out in November 2006.

The guards told the court Mr Gotovac had been aggressive and abusive. But CCTV camera vision of the incident showed Mr Gotovac sitting calmly on a stool before he was grabbed by guards and dragged through the casino.

During the incident he fell on his face and, despite co-operating with the guards, in the security office he was forced face-down on the ground and placed in a leg lock. ''It was pretty bad, I was pretty scared of what was going on,'' Mr Gotovac said.

Casino Canberra paid the Canberra man $95,000 to settle his claim but could not be reached for comment.

Mr Gotovac and his lawyer, Craig Edwards from Maliganis Edwards Johnson, said the case turned on the CCTV footage. ''Cases like this where there are four opinions against one, well, the camera never lies,'' Mr Gotovac said.

Mr Edwards said video evidence often went missing by the time lawyers and police got involved. ''Normally, those who are astute and aware and have something to hide by the presentation of evidence - it's very easy [for] them if they have control of the store, bus or Taser gun - they have an opportunity to manipulate them or lose them or for them to be lost in the bureaucratic labyrinth,'' Mr Edwards said.

Mr Gotovac's experience has led him to speak out about CCTV cameras in Canberra: ''There should be more cameras that the cops can access but cameras should be heavily regulated or monitored - you don't want things popping up on YouTube - but they should have it in case of emergencies and cases like mine.''
