Would You Shoot 2 Men to Protect Your Neighbor's Property?

[Gemini Cricket]

Ever since he fatally shot two men he suspected of burglarizing his next-door neighbor's home, 62-year-old Joe Horn has been both praised and vilified for his actions. Horn called 911 and told the dispatcher he had a shotgun and was going to kill the intruders. The dispatcher pleaded with him not to go outside, but a defiant Horn confronted the men with a 12-gauge shotgun and shot both in the back.
Some community activists wanted Horn to face charges for the deaths. Supporters of the retired grandfather said what he did was justified under the law.
