As soon as my parents fall asleep I am going to use their gun.
Why would you steal a gun?
Because a firearm is a tool for self-defense and many other things. I want to protect myself from people who wants to hurt me.
It is a crime to steal a weapon and use it on someone. You should always ask or buy your own so you don't get an extra felony or hurt your parents.
I was hoping to go and commit a crime.
You should not be going to grab your parents gun. You parents are allowed to have the gun as long as they have a gun liscense. You can not use or have the gun since you do not have this same liscense.
