How To Ensure You Don't Injure A Family Member When Using A Gun To Defend Your Home

If I use a gun to defend my home, how do I make sure I don't injure a family member?

In a home invasion it's a very good idea to know where the members of your family are, and you can't be certain necessarily of knowing everything all the time. That's one reason why I personally prefer using a hand gun with ammunition that doesn't penetrate walls, it tends to be lethal if it had to be, but it's not going to go through a wall and endanger somebody on the other side. So, that is precisely why that kind of ammunition has been developed for people thinking of just those concerns.
