He was apparently motivated by personal hostility towards people living in the dormitories. However, the residents of the city are not convinced that Jin is the culprit. A local official, who did not give his name, said that it was clear that more than one person had carried out the bombings and that the explosives had been planted with expertise. Moreover the explosions all occurred within an hour and the locations were at least 15 minutes drive from each other. The official explanation is all the more remarkable when one considers that Jin is a deaf mute who can only communicate using pen and paper.
Residents have good reason to be skeptical.
The crude use of a scapegoat is a regular modus operandi for the authorities and police, keen to avoid public discussion or debate on any broader issues. Only last September a series of small homemade bombs hit department stores and buses in the city injuring 28 people. Rumors linked the explosions to criminals battling for control of the public transport system. But the police picked up an unemployed man, claiming he was trying to extort money from the government. He was rapidly tried, found guilty and executed.
