Two more federal lawsuits filed this week accuse the security contractor formerly named Blackwater Worldwide of fostering a culture of lawlessness.

A lawsuit filed Friday in the southern district of California targets the company for a shooting in September 2007, while a lawsuit filed Thursday focuses on the infamous shooting in Baghdad's Nisoor Square a week later.

The lawsuits join a third lawsuit filed last week that makes similar accusations for a December 2006 incident.

Federal prosecutors have charged five of the company's contractors with manslaughter and weapons violations in connection with the Nisoor Square shooting. Prosecutors have not charged the company, which has since changed its name to Xe.

The company said the lawsuits are riddled with errors.
