In Baltimore, schools are closed today. Police and National Guard troops are patrolling the streets, and residents are assessing the damage from last night’s rioting and looting. President Obama today said there was no excuse for it. The rioting broke out after the funeral 25-year-old Freddie Gray, who died of a spinal injury while in police custody. Gray was arrested more than two weeks ago, and still police and city officials don’t know exactly what happened. That’s renewed calls for Baltimore police to wear body cameras. It’s an issue that’s also being discussed here in Los Angeles. Today, the Los Angeles Police Commission is considering a body camera policy for the LAPD. But some civil rights activists aren’t happy with it.
