Generally i agree, except for 2.You are on to a few things here worth discussing.
1) SWAT/Delta/SEAL/Ninja Training not always applicable to civilians. It's true: as a civilian I will never get to pick the time and place of the gunfight, while armored head-to-toe, with a stack of well-armed guys behind me, and a medevac helicopter hovering overhead if I get hit. A civilian is predominantly concerned with the reactive gunfight, where they start behind the power curve and it's more important to not get shot than to shoot the other guy. There are some very effective tactics and techniques used by LEOs and elite teams that are applicable to civilians: however, we need not accept "the way we did it on the teams" as gospel for civilian gunfighters.
2) The "Gun Guru" is dead. The advent of simunitions and the airsoft pistol has empowered individuals to find out for themselves just what works and what doesn't. While there are certainly guys with tons of experience and great ideas to draw from, with these "force-on-force" tools we can now shine the light of "combative truth" on any suggested tactic or technique and draw our own conclusions. Even better, we can find out what works best for our individual circumstances.
