Psycho

Taipei is agog after a 22 year old, second year university student went on a knife rampage at 5pm today in an underground train, killing four people and injuring twenty. He had proclaimed on his Facebook page that he was planning a big event. He'd researched the tube system thoroughly, deliberately chosen the two stations furthest apart on the network (4 minutes between them) and he ran through the carriages creating carnage with a 30cm blade knife. He left the train at the next stop and was cornered and caught.
Taiwan has the death penalty and there's been a lot of criticism of it recently because people sit on death row for years, after all their appeals have run out, without actually being executed. Last month, the government caved into this pressure and four prisoners were killed. They don't use injections there, they have a firing squad.
