I'm reading Murakami's book called Underground.
Its basically a collection of first person eyewitnesses and survivor's accounts of the Tokyo gas attack in 1995. I've never really thought much about it but its actually very scary because I take the train everyday. How these men carried out these attacks were so subtle and people didn't notice anything until it was too late. Like some of them would say everyone was just rushing to get to work, even when they noticed "strange liquid" on the floor, everyone just continued minding their own business, just thinking about getting to work on time and about the work that awaits them at the office.
"When I was out infront of Kodemmacho station, certainly that one block was in an abnormal state, people were dropping onto the ground like flies, but all around us the world carried on the same as ever. Cars were going by. Thinking back over it now, it was eerie. The contrast was just so weird. But on television they only showed the abnormal part, very different from the actually impression. It just made me realize all the more how frightening television is." - Masanori Okuyama, survivor.
Things I want to further study on:
1) By Stander effect
3) Air flows in trains
