A quote from a British officer serving in Basra. Here is the whole quote, and its context:
Basra has become riddled with organised gangs, militias and death squads, and its police force is corrupt. According to senior coalition advisers, there are around 20 different security and police groups in the city, ranging from the directorate of education police to the justice police; the governor alone has 200 armed gunmen protecting him. Some of the police units are active in organised crime and have been infiltrated by militias, others work as death squads. There are also around a dozen religious militias.
"We are in a tribal society in Basra and we [the British army] are in effect one of these tribes," said Lt Col Simon Brown, commander of the 2nd Battalion. "As long as we are here the others will attack us because we are the most influential tribe. We cramp their style."
