Paranoid, competitive and fuelled by guns, alcohol and steroids. That is how one senior contractor in Baghdad describes the private security industry operating in the city's Green Zone. It was the world to which Danny Fitzsimons, a 29-year-old former soldier suffering from post-traumatic stress disorder and paranoia, and with an extensive criminal past, returned three weeks ago...his ArmorGroup [part of G4S] colleagues welcomed him with a drinking session. A fight broke out and he shot and killed two of them...then wounded an Iraqi...Figures in the industry...say the private security business in Iraq is in a vice-like crush...But just months after the private military contractors lost immunity, the Iraqi police are flexing their muscles...[T]here is open astonishment that a man like Mr Fitzsimons, who had been sacked from two companies, Aegis and Olive, was hired again...The [UK] Government is expected to report back on a six-month consultation later this year, recommending self-regulation with international co-operation...the director general of the British Association of Private Security Companies, said that self-regulation was the best option but that a greater level of co-operation between companies was needed.
