On the other hand, the victim behaved as a reasonable man might. Regardless of any alleged criminal acts before he got chased down, a reasonable man just might try to disarm some nut who was advancing on him with a shotgun. Its a fear-for-your-life kind of thing
Hold on partner. You have your facts completely backwards. It was the jogger who advanced on the shotgun guy. It was the jogger who took aggressive action on the shotgun guy. It was the jogger who took a swing at the shotgun guys head. It was the jogger who grabbed the shotgun in a hostile aggressive fashion.
Fear for your life kind of thing? Yes, no doubt. It was the son who was in fear for his life from the jogger.
Okay, lets suppose you are walking down a street. Maybe you just stole an apple from some apple stand. But then again, maybe you didnt. Then some guy - not a cop - pulls up to you with a shotgun.
Im an old guy. I know what I would do. I would freeze, and then I would assess the situation.
But if I were 20, I would probably would behave differently. Id probably panic, and try to get shotgun guy before shotgun guy got me.
Bottom line: Dont go chasing down the street after folks with a shotgun. You are not a cop. Call the real cops.
