Sorry layout, you can not control the pattern of a shotgun while in motion. The choke can only do so much as to setup the pattern when leaving the muzzle, there are always shot that will not hit the target but surrounding areas outside the intended pattern.
The actually odd thing that no one seems to be mentioning is the use of the weapon when being confronted by someone. If this happened here, say in my state and the person was armed with a knife, there may be a chance you will end up with a murder charge. I think NY is worst than that, you may end up with multiple charges.
This leads me to another thing, how would you know the person was a threat to you unless you see a weapon, like a pistol? If you see one, would you think you have a chance of pulling a shotgun out, loading it and then using it?
First off, I can control the pattern while moving the gun, just as all those dead ducks. I only missed one all last year. Ducks are WAY faster than people AND much smaller.
Second, I NEVER carry a shotgun for protection. ONLY a legal handgun and rarely do that.
In my house I have NO requirement to retreat. It is my LEGAL refuge under Michigan law. I can, and will if forced too, use deadly force in my home. It is my right to defend the life of my wife, my life AND my property. The is one of the primary reasons we have the Second Amendment to the Constitution. Self Defense. I have a shotgun in a "safe" but "ready" spot when I am home. As well as my handgun and my wife's.
By the way Greg, you are NOT correct on the knife issue in Michigan. IF attacked OR threatend by a knife wielding attacker, having NO place to retreat, it IS legal for me to use deadly force, under Michigan law. I don't care about NY, I don't live there and seldom leave my truck when in that area.
