Between Jan. 1, 2010 and Dec. 31, 2014, Los Angeles County district attorney records show at least 375 people were shot by on-duty officers. No officers have been prosecuted for any of those shootings.

About one in four of those people were unarmed.

Law enforcement officers in LA fatally shot Black people at triple the rate of White and Latino people, relative to population.

That's the lede from Southern California Public Radio KPCC's important, interactive investigative report on "officer-involved shootings" in LA, and there's a lot more to be upset about in those numbers, too.
