Except that's it's not my assessment, it's the Mexican government's assessment.
EDIT: When the Federall'es (SP? Mexican police) say your cops are out of control, it's time to take another look.

It seemed to me that the guy was a belligerent drunk, who at one moment complies (standing with his hands on head), then turns to argue, tugs on his shirt collar (in a failed attempt to show he's unarmed, or telling the cop to shoot him there?) and shuffles slowly towards the cop. If he was trying to suicide by cop, he did it in a way that made it look totally unthreatening to me. No quick movements, hands on head, no weapon, no threats, no fists...where's the threat in a slow moving unarmed suspect?

I agree, once he was in arms reach and still advancing, he's a threat...but you must completely ignore the cop's ability to move away to make the killing in any way justified. The cop had every opportunity to keep safe distance by simply moving away slowly...why didn't he? Stand Your Ground?
EDIT:Or, the cop had the opportunity to close his car door and lock it, making him 100% safe against the unarmed drunk until backup arrived 20 seconds later.

I didn't see it that way, I (and others, including the officials in the Mexican government) saw a drunk, acting inappropriately, being belligerent when he sees the gun pointed at him and asking the officer "You gonna kill me?", to which the officer replies "no, I'm not going to kill you", then reports on the radio "He's saying 'kill me'". He did not say "Kill me.", he said "Are you GOING to kill me?" as I heard it.
I never saw him reach UNDER his shirt, only tug at the collar of his shirt, and at one point turn around and put his hands behind his back touching his shirt (but NEVER under his shirt). I don't know where that idea came from (except maybe from the cop's statement), please watch again.
I think if an unarmed man slowly advancing on you with hands on his head is a 'deadly threat to the officer's safety', we have HUGE problems, because that theory makes it legal to shoot anyone that comes near them....they don't know if they're armed and attacking, or just passing by, right?
Cops are supposed to de-escalate problems, not exacerbate them.

As for the 'murder' designation...if a citizen shot this man in the exact same circumstances, he should face murder charges. I don't give people a pass on homicide based on their job.

I'm sick like a sore throat swallow, drunk act to follow
I'll make the whole bottle hollow (what a ride!)
Rollin' wit' a open container, and one in the chamber
Ten Likwit CD's in the changer
Bettin' wages on the Lakers; yo' squad is in danger
Hoes go two ways these days like my pager
Say Hoe, my name is J-Ro, oh, you didn't know? (no)
Well, fuck you then!
I hang with cats, who chase rats, and kick tats
Hit the eightball like Minnesota fats
Got more ? than biceps, relax
Pure hoes jockin' in the studio flats
When I'm in the house, take off the wave cap for hats
Got scully from a hoochie, with lips like Da Brat
Raised in the valley of the shadow of death
So I fear none, time to anty up for the beer run

So all the ladies to the Limo, it's Tha Alkaholik car pool
Lyrics bang from thirty feet to blow y'all niggas off your bar stool
We back, to wet'cha, the flawless, the wallus
Regardless of your colors, Tha Liks are Alkaholiks

We the same three niggas that be makin' the noise
Doin' donuts in Ferraris, like some drunk hot boys

Do or die fool! Straight from the home of where we spark from
Where the weed'll leave ya dizzy like a tranquelizer dart gun
The L, not to be confused with Tinsletown
Well, I made a million dollars off this shit I penciled down
Flashy Tashy, be gunnin' from the worsest alliance
And when I die, I'ma donate all my verses to science
Do the tango, while rappers get strangled by the lone-shark
You be ridin' niggas dick, that's why you never make your own mark
I'm sober and justice, why this is my year
Screamin' "Party over here, fuck y'all over there!"
(Party over here, fuck y'all over there!)

King Tee started it off, and then came Tha Liks
Then Xzibit added hot done proda to the mix
Then Defari, "Hey you!" Comin' through, Likwit Crew
And ? gets the broom, who can sin it?
Who can sin it? Twisted and been it, but if the funk ain't in it
My DJ always submitted to spin it
If I said that I meant it, don't get'cha mouth pin it in ?
We feelin' with a penny, represent it

Aiyyo re-pre-sent, yo', re-si-dence
If it don't say Likwit, then you won't get bent
Aiyyo, dollars and cents, make the world just awkward
Got niggas in the hood, livin' next to their doctor
I'm a rowdy, mic-rocker, since the age of twenty-two
In the video, flossin', like "This could be you"
Likwit Crew, do it up, 'til the wheels fall off
Unlike these other niggas that had it and lost it
We stayed in the game, stayed hot, turned up the flame
