Student Shoots Passengers at Hirai Station with BB Gun
From Kyodo:
Kengo Naganuma, 24, lives just 40 meters away from a platform of JR Hirai Station in Tokyo's Edogawa Ward and is suspected of having targeted people there from his balcony. The police confiscated eight airsoft guns from his home.
"I wanted to shoot people and see their reactions," Naganuma was quoted as telling the police. He also told them he had done it on other occasions.
A simple lesson of cause and effect for our young friend.
