Firearms are difficult. Our justice system in this type of situation almost seems in favor of the criminal. Having a gun in your home is one thing, Using it and killing someone is another. You would have to prove your or your families "Life" was in danger, Otherwise you would be charged with murder. I don't follow the Laws in other States as they do vary, But in California, If someone wanted to come into your home and steal all your belongings, You can not shoot them...While I disagree with this because they don't belong in our homes to begin with, It is the law.
I have a lot of family that lives in certain counties So I pushed them to get CCW permits so they can carry. My sister is always armed when she goes out. Best advice I can give for fellow sisters, mothers, etc is go out and get a CCW if your city/state permits them. MUST have a clean record, and even then it is Very difficult to get, But worth it imo with our society.
