In case nobody here has ever studied this stuff, you deal with the immediate threat (the one you're facing) first (which means shoot it), then turn to whatever threats remain. Your situation is resolved when there are no more threats standing. This is basic, common security protocol. Any defensive or security school in the world will teach you the same thing.
Okay, at this point I am going to weigh in...as a security guard.
A security guard is
not a soldier. A security guard's primary job is to move a security uniform around: the uniform does most of the work. The secondary function is to answer questions. Administering first aid comes third. Damaging people is way down the list, maybe tenth.
Then, consider that this security guard is 'static' - that is, standing at a single position with nothing to do. That's dull grunt work, and probably indicates a new employee. More experienced guards will be roving, checking things and answering questions.
Current day, 97% of all security alerts are false alarms. Someone has dropped out of the loop? Double check. Still nothing? Tell the roving guard to check.
Then start to panic. [Given the info we've been given though, the guard was probably viewed on the security camera - so rather than going off half-cocked control has probably called in military personnel. This takes time though, hence why they haven't turned up yet].
Security guards almost never use guns. They are frankly the most useless piece of equipment a guard can be given. The risk of shooting an innocent (or prankster) far outweighs any benefits gained from carrying them. Tasers aren't much better. And unarmed against a war hero and street sam? He didn't have a chance.
