No matter how much dramatised violence we are fed on our TV sets, movie screens and in video games, nothing assaults our senses more than seeing real rather than concocted combat. Three minutes of CCTV footage can be more disturbing than anything Hollywood throws at us.

So it was last week, after vision emerged of an incident on July 3, 2011, when Crown security staff ''subdued'' three casino guests with terrible consequences - one death, several injuries and charges, two court cases, another in prospect, and several convictions. The footage screened on most TV news last week and is widely available on the internet. Suffice to say it's not a great advertisement for Crown. A world of entertainment? A world of pain, actually.

Video cameras record things getting out of hand at Crown.

Judge Lex Lasry, who presided at the second trial to arise from the incident, agreed to the release of the confronting footage after a jury last week convicted two bouncers of intentionally causing serious injury during the 2011 fracas, and a third of unlawful detainment. They await sentencing.

Meanwhile, the couple who survived the incident are suing the casino after a night out with their friend, Anthony Dunning, ended in his death four days later, from the effects of cardiac arrest. (Two other Crown staff were found not guilty of manslaughter last year.) The toll from this unfortunate incident continues to mount.
