Sry to derail this a bit. Here is an AR, full auto rapid mag dumps, less than a 1000 rounds, not suppressed.
The thing that bothers me most about discussions about this incident is that people are making statements that echo their beliefs before the shooting. Politicians are using catch phrases to emphasize their political agenda. A CBS producer reportedly made comments along the lines that killing country music patrons wasn't really a big deal. People are so caught up in being on the left or on the right that an objective analysis of this incident will never happen.
Experts should analyze this and find out:
Why did he do it?(Although I don't think we will ever know. We will only have suspicions.)
Why did he choose that venue?
Why did he choose that hotel?
Why did he choose that floor? Did he choose it or was it just selected by the hotel?
Were guns his first choice of weapon? Did he attempt to produce bombs or chemical/bio weapons?
If he did attempt another weapon, why did that plan fail?
How did he get the guns to Las Vegas? How did he get the guns and ammo to his room?
How did he get remote cameras in the hallways of the hotel? How did he get the stairways to his floor jammed? How did the hotel not notice those things?
How many guns did he use? What order did he use them in? How many rounds through each gun? Did the guns jam?
What type of bullet did he use?
......
You need answers to all of those questions an many more before you can make definitive statements about what did work for him or didn't work for him, and what would have caused more casualties or what would have prevented the incident. The politicians should wait for those answers before making knee-jerk reactions and only re-proposing their already ingrained beliefs. However, the won't. It is my belief that even after reports are made the politicians at the most will only extract portions of expert analysis that support their beliefs. They will ignore everything else, and still only work for their already formed beliefs.
I would guess that a lot of SWAT teams started making new plans for a barricaded shooter in a hotel room with remote cameras this week.
