The Los Angles police officer has been identified as Kevin Ferguson, who is back on the job but is not working in the field. This is probably a good thing. You can find more information in this LA Times article.
As of yesterday, the investigations are still continuing. Given the plethora of video evidence, it seems to me that if there was going to be charges against Officer Ferguson, they would have surfaced by now, but you never know for sure until he's officially cleared. My suspicion is that most of the Anaheim authorities would like to drop all the charges and make this go away as quietly as possible. Unfortunately their mayor is grandstanding, so that probably won't happen.
For those of us who are concealed carriers, there is a cautionary tale here, if you care to read it. And I'll leave it at that.
