Well all I can do is give an opinion for what's it's worth, and I agree with Dillinger and Hydro. I am slightly out of touch as I haven't done tactical stuff for a few Moons, and things evolve and change.
This gentleman is well read and regulary practices his skills. He appears to be competant in the use of the weapons he is handling and obviously has an understanding and respect for safety issues.His opinions on slings I would imagine most would take issue with, the guys from the combat school here (ex-Royal Marine Commados) took a look at it..... There are a couple of indercators, particulary in the handling of the revolver. His body language and technique is reminscent of a action shooter, which is almost as far from the real world as you can get.
I would venture to suggest that if this gentleman has, or had a background in either Special Operations in the Military, or in Law Enforcement, which I doubt why the secrecy? An active operative would not make a video presentation such as this, and if he where too the weapons would not be the domestic availability demonstrated, and a retired operative would I suggest have no need these days to diguise his identity.......I find it in character with someone with something to hide will verbally go on the attack when pressed, he knows that there is vertually no way you can verify his operational and training background.
Mind you if he continues to post these video clips there are people out there who might take an interest and have the wherewithall tto identify him, and rightly or wrongly be a lot less sympathetic that members of this forum!
I agree does not believe that he intends to damage 2nd. Ammendment rights, but it is ammunition for the anti's.........
