Thanks for the info. Without taking on the whole lot right now, one sentence jumped out at me- the one about not necessarily engaging a shooter, simply being armed increases survival chances.
How does that work? How does a gun protect you if you don't engage someone?
If you look at mass shooters, they are not looking for a gun fight. They are looking at killing a large number of people. The Sandy Hook killer looked at his killing like a video game...he wanted to get a really "high score" and planned the attack for at least 2 years......they know this from the evidence they found at his home.....dittos many others who target gun free zones..they have notes and confessions that state this from other mass shooters...
So...a mass shooting starts and you are in the middle of it....the best thing you can do is get away...but if the shooter ends up in your path, and you are unarmed, there is nothing you can do...if you have a gun, you can fire on him...and likely he will either retreat to shoot other people or he will seek cover to engage you.....that gives you time, and more importantly, the police, time to get there to deal with him...
If you want to have a real look at a mass shooting...watch Terror at the Mall...I think that is the title....it is about the muslim attack on the Mall in Kenya...you can see the entire killing spree from video feeds from inside...you can see where armed people would have had a chance to survive against the 3 killers...but died because they were helpless as the killers calmly walked up and executed them.
Also...at the Pulse Nightclub...you had people playing dead all over the nightclub....had they been armed, they could have shot the killer as he reloaded his weapons in the bathroom, or as he walked around killing the wounded....
There are many ways a law abiding gun owner can use a gun to survive that don't include rushing in and engaging the attacker directly...
