A) If the individual hasn't physically assaulted you, yet you feel threatened leave
B) If you cannot leave and still feel threatened warn the individual that you'll scream for help or threatened to call police via cell phone.
C) If in the process you do both and the individual grabs you, do what is necessary to subdue the attacker
You are still
wildly overestimating the woman's options.
If a woman waits until I grab her,
her weapon has already become
my weapon. She would have been better off not carrying one.
A knife-wielding attacker can cover 21' (approx 7m) before a police officer can draw and fire his weapon. (A lot of police get stabbed this way.) If a woman has a weapon (or cell phone) in her purse, it will take even
longer to get her weapon out.
Attacks in real life
aren't like the movies, where the threatening encounter is drawn out for additional drama and suspense. It's more like a car accident. By the time you realize it's happening, you might have time for
one instinctive movement before you get hit.
And like defensive driving, you need to be taking your defensive actions
before bad things start happening.
Don't
warn him that you'll call 9-1-1. You need to be talking to the 9-1-1 operator
before he realizes you're suspicious. Don't try to leave the area
first. Get your hand on your gun,
then leave the area. If he tries to prevent you, shoot him through the purse.
