Watch the 2 full videos before you comment further. It shows a whole lot more. I watched it from both cameras. It is very uncomfortable viewing even knowing the outcome.
The chap was terrified, was being antagonised, and hyped up by the officer's terrible commands and threats. It was plain to see his approach with the suspect male was totally different to the suspect female.
He was begging for him to screw up so he could shoot him.
I wasn't aware that in GD, you can't offer input until you're fully versed in the topic - pretty sure there are posts were people will comment and then come back and expand. But I have done as you requested sir; I have just watched the ~20 minute clip in the OP, up to the point that the other officer is taking the woman away to the squad car - what I noticed in it:
At around 2:18 someone says "more than one person", shortly followed up by talk of a female - my immediate thoughts to those two points are it can be taken two ways [IMO of course]; one that there is more than one person and the female, or that the more than one person includes the female If the latter, then would they not just say "male and female", or does this indicate that they had uncertainty about the number of occupants within the room.
There's over 3 minutes where one of the officers are shouting "occupants of room 502..." and get no response, this is followed by one of the officers being told to get a keycard. Who knows what might be going on in the room - are they simply not hearing the order, are they loading weapons, are they getting ready to shoot...
Around 6:38 one of the officers mentions "hearing two voices" - could very well be the male and female, but there's nothing more said about this.
Around 9:50 both the victim and woman are out of the room and both are heard saying there is no one else in the room - I have already mentioned what I thought about this, and the fact that all three officers keep their weapons up and positions safe; seem to show that they are still guarded on this fact. Shortly after this, the shooter makes some remark about the fact both the victim and female have shown an inability to follow instructions - I presume that this is in regards to not answering the "room 502" shouts; as the view isn't clear; so I couldn't see if both the victim and woman had got down with crossed legs and arms up before this comment. The shooter makes his first threat about shooting them, and it not ending well.
Both the victim and woman confirm to the officers they are not drunk - but they sound either drunk or stoned; in fact, the woman doesn't even seem to react to the victim being shot. I guess that fear could account for all of this though.
One thing I did notice, was the split second before the shots are fired, the two other officers you can see, both react to the victim's movement - so it seems that even they suspected he was armed, and could have been drawing a gun.
I fully agree that the victim was terrified, I think we all would be if in his place. The shooter was treating both suspects like children, if his "you're ******" sticker is real, then you can start to build up a picture of him as being itching for a reason to kill them both; certainly after having his commands seemingly ignored, prior to them coming out into the hallway.
I didn't see a difference in how the female was dealt with, as opposed to the male though - but we're all processing this horrible video in our own ways. If anything, the woman seemed to follow the shooter's barks to the letter - though the second video doesn't show her fully all the way through the ordeal.
As for begging for him to screw up - I don't know the answer to that, again [if real] that sticker on this rifle shows he's not the full ticket; it's almost like he's treating it like a R6 Siege or CoD unlock-able skin for goodness sake. If there's any information on his that shows an unstable past, then he's certainly heading towards to category of nut job, and not really the sort of person you'd want enforcing law an order, with an automatic weapon.
