Make no mistake - they have murdered him.
"Mr Justice Treacy described the murder as a "terrible and evil crime", committed "for no other reason than racial hatred".
Sentencing the pair, he said: "A totally innocent 18-year-old youth on the threshold of a promising life was brutally cut down in the street by a racist, thuggish gang.
"You were both members of that gang. I have no doubt at all that you fully subscribed to its views and attitudes."
He added that while Dobson and Norris may not have wielded the knife that killed Stephen, it was used with their "knowledge and approval". And neither had shown the "slightest regret or remorse".
The judge also said their racist beliefs and lust for violence were confirmed by "disgusting and shocking scenes" captured on a covert police surveillance video filmed in Dobson's Eltham flat.
It showed gang members spouting racist comments and playing with knives
