Michael J,
I have a problem with the scenario with the bad guy setting of the alarm. The first thing you did was to run for the phone. What makes you think he just ran away. Most cops wont come to alarms any more and the bad guys no this. It would take only a moment to search the main floor, find you and take you out. I think it would have been better to go to your nearest safe room, lock the door, arm yourself and then call 911. At least your safe at that point.
Monty,
That's a valid point. The honest answer is that, for production purposes--primarily lighting--it was more efficient to go to the phone. From a practical standpoint, it still makes sense, though. An alarm MAY bring the police (in my neighborhood, it typically does). An alarm AND a 911 call will establish very quickly that it's not a false alarm and most likely hasten the response time.
Bes of all, the phone I went to is literally five feet from the downstairs safe room. If the bad guy reappeared, I could easily duck into that room before he could "search the main floor, find me, and take me out."
We try very hard to make our scenarios as realistic and informative as possible. Please understand, however, that we typically have to make do with limited resources. If only we had that "Gun Stories" production budget...
Stay safe,
Mike
