More: Here are some key findings of the review, revealed by the Times Thursday:

Border Patrol agents have intentionally and unnecessarily stepped in front of moving cars to justify using deadly force against vehicle occupants.

Agents have shot in frustration across the US-Mexico border at rock throwers when simply moving away was an option.

Border Patrol demonstrates a "lack of diligence" in investigating incidents in which US agents fire their weapons.

It's questionable whether Border Patrol "consistently and thoroughly reviews" incidents in which agents use deadly force.

The report is especially scathing in its critique of agents who've stood in front of moving vehicles, recommending that they "get out of the way ... as opposed to intentionally assuming a position in front of such vehicles." The authors add:

It should be recognized that a half-ounce (200-grain) bullet is unlikely to stop a 4,000-pound moving vehicle, and if the driver ... is disabled by a bullet, the vehicle will become a totally unguided threat ... Obviously, shooting at a moving vehicle can pose a risk to bystanders including other agents.

The report recommends that Border Patrol bar agents from shooting at vehicles unless their lives are threatened and also from firing at rock throwers. An internal response by Border Patrol, also obtained by the Los Angeles Times, rejected both these recommendations.
