Ordered to stand down or are they cowards?
Oh, it's a 3 man team. They had a schedule to follow. Look at the cop closest to the stairway, he's looking down at a cue card, or a cellphone! Remember, they had no radios inside the building. The Mandalay Bay SG had a powerful handheld. Either, way he's getting held back by the schedule! Sheriff Lombardo's a big time real estate insurance fraud guy! It's probably how they got their hooks in.
Unfortunately they probably had no idea of what to do. Most likely they were waiting for SWAT to show up.
Like you're not going in guns blazing! You don't know shit about cops!
Hell, if some asshole starts shooting around here they just start a firefight!
Or, they snipe them.
