This article on Yahoo cites to documentation where he had emotional break downs while on duty, and asked to be sent back to eth police academy for more training. LAPD's response was apparently to ignore these instances, keep the guy on duty, and terminate his employment upon his first "violation." Gotta say that I'm smelling something even worse now. I've seen instances where bad cops (who do a lot worse than he reportedly did before getting fired), with the backing of the union, stay on the job. Wonder if we'll ever get a real story out of this...
As for the actions of LAPD in response, I'd recommend a federal civil rights investigation, but I'm not all that confident in the DOJ these days...
OTOH, the police unions, and minority officer organizations etc. and just the PC/affirmative action policies of the department itself, if there were
any merit to his complaints, I think
somebody would have taken his side, or taken him on as a "cause".
http://lapd.com/In google, "los angeles discrimination" comes up with roughly 11,600,000 results for attorneys, law firms, advocacy groups etc.
http://www.blackpolice.org/The incident that got him fired, the accusation of brutality/kicking by his training partner was denied by other witnesses at the scene, the supposed victim they were arresting for acting crazy/disturbing the peace or whatever it was, did not mention it, and the only person who testified to the kicking was the man's father, who wasn't present at the time.
Then there's the (admittedly anecdotal/hearsay) reports about his time in the military from people who professed to know him that state a similar pattern of failure, failure to work/study/prepare/learn, and washing out there as well. And severing friendships or getting angry at anyone that pointed out to him that he failed, and the organization didn't fail him.
If these are true, it would be consistent with him displaying a pattern of character deficits and some personality disorders.
If I had to bet, I'd lay four figures or a case of 5.56 on the LAPD having "significant corruption" were there some way to freeze the agency in place and lift the lid off of everything at once and have it all examined by some neutral third party. However, I don't think it was corrupt in his case.
