The lady who tried to be hero was on the news this morning being interviewed. At least the interviewer didn't call her a hero. That was pretty stupid what she did. If you notice the other council members are trying to talk to the guy and calm him down, try to reason with him, that's really all you can do. By this lady coming in and provoking the situation it could have been much worse. I remember my military roommate in college always told me the military had a saying about heroes - and that is ---> "heroes die first". I've remembered it to this day. What she should have done was leave and call police.
her problem was, she did it expecting to live.
When you are going to do something like that you have to fully commit to it and come to terms with the fact surviving your decision may not be an option.
She was hesitating the entire time, you could see the hesitation in her movement, because of that hesitation, her attempt was doomed to failure from the get go.
that and the horrible decision to just hit his hand with her purse. A better option would have been to just come up from behind and bear hug his forearm keeping the gun pointed away, while the others bum rushed him.
