Just for the sake of accuracy this Somali germ was a career criminal who despite convictions for robbery, affray etc avoided deportation back to Somalia because our limp wristed authorities considereed it to be a dangerous place. Thus he was allowed to remain at liberty here carrying on his criminal activies culminating in the murder of the WPC.
After her killing he left the UK (fleeing to dangerous Somalia) disguised under a burkha - obviously not spotted by our politically correct authorities. A couple of years later the UK managed to have him kidnapped by some militia men and brought back here to face trial. A bullet in the back of his the head would have been a more cost effective solution.
