Do your videos train dogs to hit an arm which is holding a gun? We live an area where the Bloods and Cripps have run through our back yard.

I was wondering what your opinion is on the idea that a canine should take out the weapon hand when confronting an armed suspect. I live in a neighborhood where two rival gangs live; the "bloods" and the "cripps," and there have been times when the chased suspects have run through our back yards. Some have been armed, some have not. Do you have any videos showing how to train a canine to take out the weapon hand and then bite strategically to disable the intruder. Here is a senerio: An armed suspect/intruder enters the back yard of a house. He/she is carrying a weapon (i.e. a gun, knife, and bat etc.) Isn't the canine in jeopardy if the canine bites everywhere on the body, but the weapon is still in the hand of the intruder? Isn't there the great possibility that the dog can get killed? Please give any thoughts and opinions on this matter. Do you have any videos or are you willing to show on video how to train a canine to take out the weapon hand? Do your videos give the viewer adequate knowledge to train a personal protection canine, police canine, etc.
