So basically if you own a business you should just let it be destroyed. Because heaven forbid you try and protect YOUR property. Picture if they tried to burn down Scwaab meat company. It’s been it that building for like 100 years. Oklahoma needs a law that clearly states you can use deadly force to protect property. Because I can guarantee this crap will spread everywhere.
I believe that what people were trying to say is that if the OP was looking for a clear cut definition of when it is ok to shoot someone and when it's not, he's not going to find one. The law allows for self defense, but the responding officers, the D.A., the judge and the jury might have different interpretations.
You don't need a law specifically to authorize deadly force to protect property...deadly force is already allowed for to protect yourself. If you are threatened during the course of lawfully occupying your property then you would be able to argue self-defense.
The law will NEVER be written to say if person A does X then person B can kill them.
