Interesting. I didn't see the topic drift. I had hope that some of the many former police-FBI-and military with combat experience would have responded. Maybe they still will.My feeling is that these promoters have been advised by their lawyers not to have any kind of counter sniper presence at these events, for all of the usual list of reasons, which, at least to me, are not credible in the war we are already well into in this country. It should be noted that high officials of all kinds have these teams deployed whenever they appear at gatherings of any size. I think that this event will be the beginning of big change in the U.S., and I don't thing that it will be good.
The liability of a promoter hiring what is effectively a counter sniper team would be huge, but there might be some merit to the local police department using events like this as an exercise for their sniper teams.
In this case, snipers placed two or more surrounding buildings covering different sectors probably would have detected the guy when he first broke out a window on the 32nd floor, and if not would have detected the muzzle flashes. He was after all doing some fairly high angle shooting that would have prevented him from staying too far back inside the room. "Open" windows in buildings where the windows don't open will gather attention, and while not readily visible from the ground, they are easier to spot from adjacent buildings.
In addition, had a team been in place on his roof top, the response would have been much faster as they would have been on site and could have entered the building from the top and been directed to specific room by observers on other buildings. Which is to say that pre-positioning officers on all the roof tops in a finite area is another method of quickly engaging a shooter in a high rise building, even if snipers are not used.
I'd much rather see SWAT teams being used this way to maintain proficiency than being used to serve warrants or execute no knock raids to arrest suspects.

One challenge however in this type of event is that police snipers differ from military snipers. The engagement range for a military sniper (in other than a DMR role) starts at about 500 yards as anything less tends to increase the risk of detection, with no material increase in first round hit probability.
On the other hand, the average engagement range for a police sniper year to year is around 75-80 yards. The challenge in police sniping is that you're shooting at a 2 square inch target (looking for immediate incapacitation through a hit to the brain stem), often through glass, and often on command. That's just as challenging as shooting a torso sized target at 10 times the range.
But...if you want to use police snipers in a counter sniper role, you'll have to train them for that role, in terms of detecting the target and then engaging him effectively at ranges up to several hundred yards in some interesting wind conditions.
Personally, I think it's a good idea. It's also practical, and cost effective given the shear area that a single team can cover from a roof top.
