Joliet Marine Sergeant Manuel Loggins fatally shot by California sheriff's deputy - WGN
Deputy Says He Shot 'Irrational' Marine to Protect Kids in Car - San Clemente, CA Patch
It's amazing what you learn when you read articles that are not cherry picked.
That is true, however the deputy has changed his story at least twice. The Sheriffs dept has also changed its story at least once. So far. Based on what I've read this is a bad shooting. I have a friend with the Riverside PD and he feels the Sgt. over reacted as well.
Most likely it's a poor training issue, but with the investigation ongoing it will be awhile before we know anything.
