Another Month, Another Thug Killed By Metro

For the 6th time this year, a Metro police officer has shot and killed a man, this time near Mojave and Washington, in the northeast area of town.
From the LVRJ: Las Vegas police shot and killed a 35-year-old man Friday morning after a domestic dispute in the northeast valley.
The fatal confrontation unfolded about 7:30 a.m. when a neighbor reported a disturbance at 2917 Theresa Ave., near Washington Avenue and Mojave Road.
Two officers arrived and saw a man pinning a woman against a bedroom wall and wielding scissors in a threatening manner, police said.
The man refused the officers' commands to drop the scissors and surrender.
Officers twice tried to incapacitate the man with a Taser but the attempts failed, police said. The man tussled with officers, gaining control of one officer's stun gun and trying to grab the other, police said.
One officer shot him several times, police said. He was given medical aid but died at the scene.

This is the the 6th killing by Metro this year. How many other police jurisdictions have this many officer involved shootings this year? Further, why are so many people taking on Metro to the point that the officers have to shoot?
I do have some questions about this shooting though: How did the suspect able to get a hold of an officer's Taser and was that Taser operable? Remember, that the suspect was Tasered two times, so was this Taser able to be used against the officers?
Did the officers think that the suspect was going after the officer's gun or Taser.
Was the woman who was being threatened still in danger at the moment of the shooting? If so, wouldn't it have been more prudent for the officers to back off until more officers arrived to subdue the man?
Did the Tasers have the camera feature on it so we could see what was going on?
Was the man given medical immediately after the shooting or did the cops delay treatment from the fire department? There is a fire station with a paramedic ambulance and engine within a few blocks of the shooting, so if the guy was shot in the upper torso, he would have had to bleed out pretty fast not to survive the shooting before the fire department got there. If the guy had a pulse when the fire department got there, why didn't they scoop and go and get him to a hospital, such as North Vista which is only a couple minutes away from the scene?
How big and what type of scissors were being used by the suspect?
7:00 is shift change at Metro, did that affect the response by Metro. What was the response time by the officers and back up?
Just some questions I feel that need to be answered but on the face of it, it sounds like a good shooting but as we have seen in the past, facts can change by the hour or day.
