What Is Disparity Of Force?
In some states, you can be charged with a crime if you defend yourself with "too much force". It is nothing more than Prudence! It is bringing the best defense with you. It is being what the Constitution assures you the impunity to be...PREPARED! (That is what the Second Amendment is all about - being prepared.)
Pragmatism is called for here, not level of force. The desired end is to have the means to defend one's self and family from any force bent on harm. How much "reckless disregard for life" should one have to put up with before he halts the reckless disregard for life his attackers are dispensing all over him?
I've only got one defensive weapon on me most of the time. I don't have the luxury of carrying one for each "level" of threat being foisted upon me, nor do I think I (or many of the rest of us) have the luxury of time to decide which level to apply, hoping the perp doesn't raise the level of threat when you start defending yourself with a weapon inferior to what he pulls out after you get started!
I'll defend myself and family with extreme prejudice. I don't go to the mall with a Mini Cooper, a sedan, and an SUV. I cover all my options with the tool that will cover it all. I take the SUV to the mall. Call it prudence. Call it practical. Call it common sense. You can't call it unprepared!
