I can tell you what this 59 year old 5’4” half serb woman would have done. I would have closed the door, called 911, then opened the door and kicked that old perv’s ass, saying “the police are right behind me” before I hit him with whatever I could find.
I have already addressed this issue. A mind this depraved and savage could VERY likely use the little boy as a shield. Only a concealed expert marksman-sharpshooter can settle such an event.
Rushing would have to be CONCEALED until the very last-second. Not likely if McQuerey was spotted.
Next, using the boy as a shield, he threatens to crush the boy or such (”Dog Day Afternoon”) he orders the pursuer down to the floor or much much worse. A very dim scenario.
I repeat: only a concealed expert marksman-sharpshooter can settle such an event.
If McQuerey had NOT been spotted, he THEN could have cell-phoned (perhaps even photo-sent..still needs to be concealed to protect the boy,) and then positioned sharp-shooters brought in.
