England ? A British coroner reluctantly agreed Friday to a U.S. request not to show in open court a cockpit video capturing the horrified reaction of two American pilots in Iraq after they fired on British troops.

But Oxfordshire Assistant Deputy Coroner Andrew Walker made clear he was doing so only in the interest of speeding up the inquest into the death of Lance Cpl. Matty Hull, who was killed when his convoy was strafed by a U.S. warplane in southern Iraq on March 28, 2003. Four others were wounded in the attack,

“If it were not for potential delay and distress this would cause the family, I would not be willing to be bound by an agreement between the U.S. and the U.K. on the use of evidence I consider crucial,” Walker said.

Walker said that, despite his own reservations, lawyers’ representing Hull’s family did not object to U.S. demands that the inquest play video only behind closed doors. It will be shown to the coroner, select witnesses and lawyers representing the family and Britain’s Defense Ministry.

The Pentagon previously had said the video was classified and could not be shown, but changed its position last week after a copy of the video was leaked to a British newspaper and broadcast.
