According to the article: "The resident showed quite a bit of restraint. He continued to yell at the suspect to leave the house and said he was armed. The couple even locked themselves in a room to try to avoid a confrontation. They had no way of knowing if the suspect was armed. The resident was clearly forced to shoot to defend himself and his girlfriend."
