Please quote the law that says this. If you can't, then it doesn't and what you're saying is just conjecture.The law says that you may use force to stop a felony.
People, be careful when you say, "The law says..." because if you're wrong, you're going to jail.
In most states, the law does say that you can use reasonable force to prevent a felony. It very rarely says you can use deadly force. There is a vast difference between reasonable and deadly force. Take some time to know that difference and how it's applied in your state.
Internet bravado and knowledge gained from facebook very likely won't keep you out of prison.
