I disagree with your assessment.

Who said anything about tip toeing up behind anyone? Guns are ranged weapons. The range involved in that lobby is small. Any shot would have been 7 yards or less (and probably half of that figure), and the cop had the initiative. A single well aimed shot to the head, problem solved.

Screaming "Freeze, police!" was arguably stupid, but no more stupid than just waiting for some guy to open fire on a crowd of people because you didn't act. There are just far too many massacres nowadays for a cop to ever assume that a guy with a gun and mask won't open fire at even the slightest provocation. I am not of the opinion that cops should let armed robberies transpire as they sit idly by.

Opinions vary, that's mine.
