I found this today, it's a collection of all his legal and LAPD files:
DOCUMENTS: Deposition, Legal Papers Challenging The LAPD - Los Angeles Local News, Weather, and Traffic
The most interesting one is "Dorner Interdepartmental Correspondence Oct2008" This is the investigation of the incident and his claims. Very interesting reading from the Detective who investigated his claims.
The video at the top shows an interview with the suspect (which the Detective in the investigation above chose not to interview as his mother advised was mentally ill). The interesting thing is that the victim, while clearly mentally challenged, does in fact state he was kicked in the face by the female officer.
I'd say that there really isn't sufficient evidence to say the kicking did take place, but there at least is reasonable evidence to say that she might have kicked the suspect. Officer Dorner, it seems to me, made the allegation in good faith. I agree that his report that day didn't mention it, thus he either lied on that report or subsequently when he alleged the kick took place, but I'd have been willing to give him some credit that he was new and delayed reporting due to internal conflict.
I'd have likely given him a suspension for a week and sent him back for the "reintegration" training he evidently had been begging for (see the PDF mentioned above, page 15). I just don't see why they fired him for trying to report something he seemed to feel occurred when the victim's statement does support it (even if the victim in this case isn't 100%).
Just my $.02
In any case, there is no justification for doing what he did. He seems like he needed some mental health help himself. I hope he turns himself in or is arrested soon before anyone else gets hurt.
Also, I believe that the LAPD officers need a crash course in understanding that a Blue Toyota Tacoma is NOT a Grey Nissan Titan... I didn't realize that they are allowed to open fire and light up a vehicle without actually identifying the occupant is, in fact, a hostile.
