If Mr. Horn was in danger when he was 10-15 feet away from the two criminals in his front yard, then his use of deadly force would be justified and he should not have been indicted.

If the two men that Mr. Horn had just witnessed commit a felony were not a danger to Mr. Horn, then he should have been indicted.

Personally I believe that he was in grave danger because in 1 or 2 seconds, those guys could have been all over him. I think that he is darned lucky to have survived that day. He should have stayed inside until he was sure that the guys were far enough away that they couldn't jump him.
