F.B.I. Says Guards Killed 14 Iraqis Without Cause

By DAVID JOHNSTON and JOHN M. BRODER

WASHINGTON, Nov. 13 — Federal agents investigating the Sept. 16 episode in which Blackwater security personnel shot and killed 17 Iraqi civilians have found that at least 14 of the shootings were unjustified and violated deadly-force rules in effect for security contractors in Iraq, according to civilian and military officials briefed on the case.

The F.B.I. investigation into the shootings in Baghdad is still under way, but the findings, which indicate that the company’s employees recklessly used lethal force, are already under review by the Justice Department.
