Not suprised because it was in Delaware.
BTW, as I found out recently, while here in AZ it is illegal to use deadly force to protect property, in Texas (under certain circumstances) it is not.
However, as the facts have been presented here, this guy had no reason to go for his gun. It doesn't sound like he, anyone else or his property was in any danger.
And I also agree with Funked, I'm betting there's more to the story.
