~I don’t believe you can set traps for people and then claim self defense when they take the bait!~
Sure. Not to mention it is not clear was the victim willing to steal from him or probably went to inform he has forgot to close a door and left his property exposed.
No self defense in this case if the factual circumstances are described properly in the article.
This guy simply wanted to kill someone and he did.
Seems like that!
What is worse, is that he bragged about how he was going to trap and kill someone before he did it. That is more than stupid.
