Regarding dignitary protection, especially that of the President of the United States... Have faith; while someone willing to die to achieve their goal could possibly succeed -- even then, it'd be a challenge.You know the more I watched this, the more I realized something, even with all that firepower and such, the man is still exposed to a good sniper. I wonder if they thought about that. Weapon doesn't fire with the guy firing it.
Remote control, always a chance for a screw up that way also, but at least no individual to take out.
Still, even if no camera could have caught it, the camera could have caught the damage it did to a wall or car while it was going on, not the actual footage of the bullets leaving the barrel per say.
Among other things (and this has been discussed openly elsewhere), about the only thing left from Cadillac on the President's limo is the logo on the front grill. The work that the guys and gals on the various protective details do is mind boggling; I know a guy who quit Diplomatic Security Service because he decided he wanted to actually see the house he was paying for more than a couple days every several months!
