Officials say none of the Los Angeles police officers who pummeled protesters with batons and opened fire with rubber bullets at a 2007 pro-immigration rally will lose their jobs.

Police Chief William Bratton had asked for the firing of four officers but said Tuesday that the stiffest penalty imposed by a department disciplinary board was a 20-day suspension for one officer, the Los Angeles Times reported.

The chief does not have the authority to remove an officer, he can only send them to a disciplinary panel which decides on punishment.

Attorney Luis Carillo who represents 40 of the demonstrators calls the decision a "slap on the wrist" that "adds insult to injury."

The melee in MacArthur Park cost the city $13 million in legal settlements.
