In handing down the ruling Presiding Judge Satoko Shotokuji said Qin had admitted to writing graffiti on a wall, and described the action of destroying the violins as one committed by someone with a strong hatred.  
In August 2016, the victim, Daniel Olsen Chen, posted a video about the incident. He has said he is slowly working on fixing the trashed collection – but has asserted it will probably take him the rest of his life to complete.
