You could say live by the sword and all that but honestly its a terrible shame this lad died so young, everything in front of him, tragic for all involved.
I can also see the other side of the coin too, these idiot bikers are part of a bigger problem of anti social behaviour and crime, think about the poor person who has to pay off a motorcycle he doesnt have, his insurance now a nightmare, he may have depended on this bike to get to work.
The vandalising of the shrine however is most likely carried out by youths of a similar ilk and not by decent people.
