Everybody seems to be a participant

I watched some news programs on an incident which a young guy killed 7 people in Tokyo. The fact is that 7 people were killed and they never come back to their families. What a sad and fearful incident... and many people who were there took photos by mobile phone. They just stared how the things were settled after killing and sent the photos to the media. The media use them as scoop photos. Some people who were there talked how crazy the scene was with their excitement. The way of their talk... I can't help thinking if they really consider the families' feeling.
