Other than making fun of the guy, what's the point?
Let's have some real critiques.
The point, in General Gun Discussions, is not much that I can see other than some light-hearted entertainment value. Were it in Strategies and Tactics I might be inclined to critique as follows:
1) Just because your heart is in the right place does not mean that you are doing the right thing. This video illustrates the true value of professional training regardless of how good you think you have become on your own.
2) Some of the tactics he is attempting without much success are very good tactics. They are simply being employed in a grossly negligent manner. Reiterates the need for training.
3) Shooting on the move is a good thing. Using appropriate techniques for movement is even better.
4) You can be completely right in your motives, i.e. shooting an attacker. You can also be completely wrong in your handling of the incident, i.e. punching and pistol whiping your target after ventilating it.
5) You should really only control one weapon at a time. Guns and swords are generally not deployed in unison.
6) Primacy is very real. The first way you learn and practice a skill is the way you will generally revert when lives are on the line. If your tactics are less than stellar, you can imagine what your results might be.
7) It is not the number of rounds you fire in practice. It is the quality of your practice that counts.
8) It is good to shoot from awkward positions. It is not good to induce them as a standard.
9) Shooting fast is not a substitute for fluid motions producing accurate fire.
10) There is much to be said for shooting with a buddy who can critique your shooting as you progress.
