Surely by now you have heard about the ex Los Angeles police officer suspected of shooting three police officers early Thursday, one fatally. He is also a suspect in the shooting of a couple in Irvine over the weekend.

The suspect, 33 year old Christopher Dorner is believed to have written an on line manifesto on what authorities say is his Facebook page, threatening to harm police officials and their families, law enforcement sources said. 

An excerpt from the manifesto reads as follows:  "I know most of you who personally know me are in disbelief to hear from media reports that I am suspected of committing such horrendous murders and have taken drastic and shocking actions in the last couple of days," the manifesto reads. "You are saying to yourself that this is completely out of character of the man you knew who always wore a smile wherever he was seen."

David Pighin, a neighbor of Dorner in the Orange County community of La Palma, said the ex-officer kept to himself and left his house and his black Nissan Titan, outfitted with tinted windows and custom rims, impeccably clean.

Dorner has no children and court records show his wife filed for divorce in 2007, though there's no evidence one was granted. Pighin believed Dorner lived with his mother and possibly his sister. On Wednesday night, Pighin saw a white van with two armed SWAT officers in front of Dorner's house and later learned about the manhunt.  

The manifesto included some 40 targets and warned that their families will be harmed.

"I never had the opportunity to have a family of my own. I'm terminating yours," the manifesto says.

So I have to ask the question what made this former Navy reservist and football playewr to snap like he did?  Perhaps the answer can be found inside the mkanifesto where Dorner rails against the hypocrisy of black police commanders who crack down on their white subordinates and catalogued his experiences with racism and injustice, beginning with a schoolyard fight at his Christian elementary school and ending with the disciplinary process that led to his dismissal from the LAPD in 2008.

There is no excuse for his actions and I for one hope that they catch him before he kills again, and before some street justice is metted out to him.
