Police: Man shot teens in self defense

In Pennsylvania, three 'teens' decided to rob a sixty-five year old man. The three 'teens' knocked him off his bicycle and two began to assault him. He pulled a handgun and shot two. One 'teen' is dead, another in the hospital, and the last in police custody. The victim, the sixty-five year old man, has not been charged. The news story makes it sound like the 'teens' were children. Sorry, when they decided to assault and rob the bicyclist they entered adulthood in what was for at least "16-year-old boy", a very final way.
