She was not LEO nor security. After the fact, the church moved to protect her by claiming she is a volunteered security. Sadly, the church shy away from her after she came out. Few of my relatives stopped going to that church afterward.
But in the Utopian gun-free world it's all sunshine, rainbows & unicorns. There are no bad or rude people because they are not afraid you see. Everyone gets along, plays nice and shares with others. It's only common sense! [Bang]
I think it's also likely in many cases where a firearm is used by a private citizen to prevent a crime no shot is fired and becomes statistically invisible. That and it doesn't sell many papers.
Most places these events happen, are gun free zones where most of us follow the law. But someone might have already posted this, I'm just too lazy to read everything. :)
IIRC there was a shooting a few years ago at a mall in Utah. I believe a CCW holder engaged the shooter and kept him at bay until LE arrived.
Historically when a shooter is met with force they either capitulate or off themselves.
Jeanne Assam was a church volunteer with a CCW, armed with a pocket pistol. She was a former LEO.
It is noteworthy that her shots did not seriously injure or even disable the shooter. However, as is often the case with these events, when faced with armed resistance, the attack stopped. In this case, the gunman took his own life. Knowing what we know about most of these killers, once the bullets start flying at them, they give up quickly.
The OP has a great list. The reason these are not such major news is specifically because of the presence of the armed citizen.
Here's one where a man gave his life doing just that. http://en.wikipedia.org/wiki/Tyler_courthouse_shooting
I firmly believe he stopped others from being killed that day.
My opinion is that there is a hidden agenda from foreign governments to disarm the American populace. It would make it alot easier to forcibly take over the United States of America if we were unarmed citizens. We don't need more restrictive legislation, we need better security in our schools, theaters & shopping malls! And yes I am willing to pay higher taxes for police at schools. The media and its views are distorted (more influence from the foreign hidden interests).
