Another stabbing and another set of assumptions about the presumed guilt of the victim. Phases like 'If you live by the sword...' and 'most of these youths belong to gangs' make it seem as if the victim was probably just asking for it.
At present I don't think there is any evidence of gang membership by the victims, in fact most reports suggest this is not true (earlier reports made the standard set of assumptions about a young black man dead).

Apologies for the link to the Daily Mail which provides some possible background:

Anybody can be a victim of knife crime, although it is clearly more likely in certain estates or even high streets not that far from Forest Hill.
