I have sound,.. a single shot maybe two (first one muffled)..at :03
...at :30 seconds a barrage of fire (whatever they saw, multiple cops fired at once)...
Video quality is too vague to second guess.

 I'd need more information to make an assessment as I don't feel watching cr@p video footage gives me enough to say.  It's like somebody watching your motorcycle wreck and telling you what you did wrong, and that they would have done better.

 The issue with a lot of these is the perception of threat, not the ability to "catch" someone.  We do hundreds if not thousands of these exercises a year depending on the contracts, and part of the exercise is what we call "rapid pull" where a Subject quickly pulls out a phone, gun, knife, wallet, or their pants up etc.

 A Subject will almost always get shot because of the speed of their movement, and their unwillingness to cooperate.  The chances of being fired upon during a Rapid Pull are reduced if one has been cooperative, and are the least likely if facing away from the Operator(s).

 Everyone and their grandmother says they would do better, or had comments like "shoot the weapon out of his hand" which is why back in 2009 we started a civilian participation program that allows the regular person to do the same drills.  Their performance, historically is no better once they have to put their body where their mouth is.

 I've been shot with a cellphone just as many times as I have been shot with a knife, and for good reason in my opinion as I see no reason why I can't shoot someone from the ground.  

 This doesn't mean that Houston was in the right here, it just means my personal experiences with this stuff provides a less black and white response type than what a lot of people want to hear when they watch a video from their couch.

I'd LIKE more details.
But
From what I could see
I didn't see what I called
A reason to shoot someone.
No tasers, bro?

"And exactly HOW would having a taser that has been deployed be a problem?"

 Depends on the Taser type.  The newer ones carry more than one discharge.  

 I'm not saying what was done here was correct, and I don't really know how to make sure that is really really clear, but the following comment is not intended to say anything here is right or wrong, it is just a fact.  Again, I am not saying that PD acted right or wrong.

 If a suspect gained control of a Taser that had a charge and cartridge remaining in it, I would not choose hand-to-hand over using a firearm to stop the suspect.  A barb in the eye could be fatal.

 This statement is not saying PD did anything right or wrong, it is only in exclusivity clarifying that Tasers can be lethal, and can carry more than one shot.
