SAN DIEGO (AP) — The U.S. Border Patrol’s parent agency has released a critical report that it commissioned amid complaints that agents used excessive force, a step that the new commissioner says is part of a commitment to transparency.

The report by the Police Executive Research Forum that was released Friday says some agents are suspected of intentionally placing themselves in the escape route of assailants in fleeing vehicles before firing guns. It also says some shootings of rock throwers were questionable, especially when the attackers were hurling projectiles from across the border in Mexico.

The report was released with revised guidelines on use of force.

The Customs and Border Protection agency steadfastly resisted calls from members of Congress and immigration activists to release the report after it was completed in February 2013.
