You say "they", but you are talking about an LAPD incident. The people in charge of the investigation the article is referring to where Dorner may have died is the San Bernardino Sheriff Dept. But while we are on the subject... What the LAPD did to those women was incompetent. I hope those cops get fired and those women get paid. Being nervous isn't an excuse to gun two people down for no reason.
Before you lecture me, you should be aware that I've been on an LAPD ride-along in Ventura County, the West Torrance neighborhood where the Koreans were shot is one I ride my bike through weekly, and the Big Bear cabin where Dorner went down in flames is a couple miles from my sister's cabin. To somehow imply that the incidents aren't related betrays an ignorance of LA culture. I talked to a San Bernardino cop who defended a shooting in San Mateo 500 miles away. They all bleed blue.
