If your kids are playing with guns, then as a parent you have failed. No simpler way to put it. You were warned not to let kids play with guns for literally years, and now April 8th came, you're still letting them play with guns. I think in this analogy its time for Child Services to come alleviate you of your kids, since you cant take care of them and have failed to follow simple. Don't give me that "its impossible, im too integrated into my ways". No, its possible, you failed to work that cost into your business logic.
No one wants to see children get hurt, but when their legal guardian has sit idly by for years after being lectured, its time to up the ante before that 0day shoots you in the face. This one might shoot you in the foot, but its a lot better than the next one which might be a face full of buckshot.
