I've taken defense classes and while all helpful I don't want to ever be that close to someone able to touch me at all...

Therefore my Glock. 357 does my fighting or my 9mm....

I've studied plenty on how to break the hold of someone from behind or in front and the second I'm free its bang bang time, period....Not waiting for what else may be coming...

But thank you for the refresher in how to fend off or yes, the easiest ways to snap the neck, put the cariledge of nose into the brain etc..
In that situation you can panic if you don't know how to combat an attacker...
