I do not blame the car that a drunk driver drove when he or she killed someone. I blame the person. However more times than not, they probably didn't buy the car thinking they were going to run someone over, or plan for months to commit the act, or wake up in a jealous rage.
I do not think that it is right to compare gun laws to laws for drunk driving.
Again, i do not believe in a full ban on guns. And yes, i know they will still be obtained by criminals who want them illegally. However, how many crimes with guns involve the mentally ill getting ahold of a family member's gun. How many look like a well functioning human being and turn out to not be? How many are jealous wives and husbands? How many are kids that don't know anything more than tv and video games? Gun laws should come with restrictions and education, just like drugs, cars, and more. Hell we teach our kids more about sex than we do about violence.
Very specially, it should not be easier to get a gun than get a marriage license.
