In fact, your good friend not only shot an unarmed man to death, changed the version of events, then it's discovered his two young girls were held about 13 hours without legal representation or even their mother present.

In addition, it seems inordinately clear, the local government "Officials" in Orange County are intentionally stonewalling this investigation.

Sounds like NCIS is investigating! That should make things interesting. I would bet that the Marines are not happy about the murder of one of their own.

I would not only be filing a legal claim, but be seeking prosecution for murder on this killer.
At the end of the day though, he is just a contractor, the city taxpayers are going to end up paying through the nose for this criminal, all while he continues to collect pay and will probably be back on patrol shortly!
