Hail Britannia
To make a long story short, some British soldier (who were not in uniform) shot some Iraqi police, but were detained by other Iraqi police and put into jail. London claims the detained British were "freed after negotiations", but that process seems to have included the use of tanks and helicopters to blow a huge hole in a wall of the prison they were being kept.

It's nice to see how sincere the occupation forces in Iraq (especially the Brits) are about allowing Iraqis to rule their own country and to enforce their own laws in it.
