Anyone that owns a firearm hopes that the only time that they ever find themselves using it is when they are doing target shooting or going hunting.
Nobody, despite what liberals would want you to believe, ever wants to have to pull that trigger when it is pointed at another human being.
No decent person that has ever had to do that would go out and have drinks to celebrate having to hurt someone. That being said, people have the right to defend themselves or the people around them.
Many years ago, there was a story that I was told by a coworker at the job I was working at the time where he said that he had a justifiable homicide on his record.
So the story goes, he was going over to visit his sister when he walked up to the house to see the door wide open and his sister yelling for help.
He walked in on his sister being raped with a knife to her throat. He told the guy one time to back away and he got up to go after him with the knife. He drew his weapon, fired and shot him in the chest.
The police cleared him initially and then hours later when the man confessed to why hew was shot before he died having the bullet removed.
The point is, when you aim to do harm to someone or to commit an act you know full well what might happen if things go wrong for you and nobody should cry on your account.
