both [the stabbed and stabber] attended that course carrying knives

Makes sense - it was a knife awareness course.

The defendant's blood and DNA was found on the weapon and DNA from the victim was also present, jurors were told.

Stabber needs some extra training - IF he got stabbed with his own knife. If both stabbed the other, then perhaps both had adequate awareness.

"That defendant does not dispute killing Hakim Sillah, nor could he," Ms Nelson said.

"He says he did not intend to kill or to cause really serious harm and told the police in his caution interview that he had acted in lawful self-defence. [He] had intended to stab Hakim Sillah in the arm, but he moved.

So perhaps more training IS needed. But not awareness, possibly just aiming? Then again, dude did manage to off the other guy with just two good stabs.

Me, I have never been to a knife fight training class. Handgun and rifle training - sure.

Although the majority of black boys in London achieve well in school and thereafter, a few things cannot be denied: black boys in London are massively over-represented in stabbings; black-on-black violence is significantly gang-related; gangs in London are crime-focused; the age of recruitment and grooming of young people for gang activity is dropping to primary school levels.

BLACK DADS MATTER - OR THEY SHOULD!

The attacker was conveniently "17 years old."
