After reading through this thread some truisms came to mind:
Situational Awareness: If your S.A. is good, chances are, you will never get to the situation where you are on your knees, at the mercy of a criminal. I used to be a Corrections Officer, and my duties had me trying to keep order while outnumbered 48:1 by those who have proven/been proven to have committed various crimes bad enough to get them into prison. Some advice: never give a threat your back. If you can be approached from the rear without knowing it, you are in danger. In the prison, if a prisoner was within arm’s reach, that was considered an “assault” and the prisoner could be written up for it. Prisoners don’t care about being written up. If they want to get to you, nothing is going to stop them. So you stay out of anyone’s arm’s reach. When in a dangerous or unfamiliar situation you watch people’s faces, eyes, gait, clothing, and anything else that conveys emotion or intent. That brings me to my next topic:
Profiling: Again, when in an unfamiliar (or even familiar) or dangerous place, always “read the room” and your gut will tell you whether you should be in Condition Yellow, Orange, or Red. And as General Mattis said (or what has been attributed to him as saying) “Be respectful but have a plan to kill everyone in the room.” If someone sets off your “gut” or just looks like trouble, you better have a plan to neutralize that person. Hopefully you won’t have to, but having that plan is better than being taken by surprise (“Everyone has a plan until they get punched in the face.”) Make sure you don’t get punched in the face. I take the train to and from work every day and I do a very quick assessment on everyone in the same train-car as me. I try to stay in a neutral stance with the train door behind me and my bike in front of me, that can be used as a shield or a weapon.
Mass Shooters: history and after-action reports tell us that most mass shooters do not expect anyone to fight back, and when they do, the shooter tends to move on to easier targets that won’t fight back. Also, when confronted by police, the shooters tend to off themselves. This tells us that shooters are cowards who don’t want, and cannot sustain anything approaching a fair fight. So fight back. Throw chairs, heavy objects, anything that you can use as a weapon. Hiding in a place with only one entrance/exit is just waiting to die.
Crowds/riots: These cannot be predicted, so avoid them if possible. Get away as soon as possible. If you cannot, and have to fight, that is when having at least two extra magazines comes in handy. If I am carrying two extra magazines, that means I have 37 shots. I don’t know about you, but I don’t want to be #1, #2, or any number of people who have been shot trying to take down an armed person. Who wants to be #38? Are you going to wait around to see how many others in the mob get shot before trying YOUR luck? I don’t think so. The human survival instinct will eventually override the mob mentality.
As many others have posted, if you end up on your knees, having been put there by an attacker, you were either negligent in your situational awareness and preventative measures, or you were taken entirely by surprise and force (think shock & awe) and you’re now at the mercy of your attacker. The only thing you have left is to lunge from your knees and hope to take down your attacker. If you can, that’s where your ground fighting skills come into play. Hopefully you have some.
