What if I told you that the very first rule you learn in Firearms Safety 101 is to never, ever, discharge your firearm unless you know where that projectile is going? To know exactly what you're shooting at?
And you also ignored the 2nd piece of my post, which is below. This is a great way to have your spouse or child killed when coming home late at night.
“Well, you know, my shotgun will do better for you than your AR-15, because if you want to keep someone away from your house, just fire the shotgun through the door.”
That quote is when he was paraphrasing himself talking about shooting off the balcony. Am I saying you should do that? No (although honestly, makes as much sense as what many people think they need for self defense). DId he ever used the words blindly or wildly like you suggested? No, he did not, you still just made that part up.
