From start to finish: grab cell phone, dial 911, relay pertinent data, scream your CYA statement for all to hear.....we're at what, 7-8 seconds on the short side? 7-8 seconds of making noise......that's just about the same amount of time it would take for a properly motivated individual to traverse from a front door to wherever you're hiding and kick that door in....all while you're not paying attention to his movements.
