Already ran that experiment here, at Trolley Square. Off-duty out of town police officer had his 1911 with him, in violation of mall policy (and no spare magazine). He made the shooter much more interested in staying out of the way of bullets than finding victims. SLC police arrived at warp 9.3.
There was another hero at that incident. He ran from store to store, telling them to get everyone in the back and lower the grate. That put many of the customers out of reach of the shooter, and cut off much of his freedom to move around the mall.
One of the most radical mosques in the country is reputedly located in SLC, and is well known to police.
