The Al Jazeera journalist asked him if he thought he might end up in jail one day. "Yup," he responded. "Cause I might get into a fight with the n*****s and I might kill them."
He also described witnessing his father abuse his mother.
"My dad had the chair up against my mum's throat, and my sister broke it up, and the police came and arrested my dad."
Four years later the documentary-makers revisited Sirius, as he was about to turn 15, to find out if anything had changed.
His dad was released from jail, went back to jail, and was then released.
Both his parents lost their houses - and his entire family of six were all forced to live in a tent.
"We were all living in this, but before this tent, we had two little tents," Sirius said.
"We were homeless for ages, we always hoped we would get a house, and we finally got one two weeks ago.
"We had a new born baby living with us in the tent - my little sister."
Sirius made a stark admission: that he still thought prison was his future.
"I just know that I'm going to go there, all of my brothers have been there, my dad's been there, my uncle has been there, I just know I'm going to go there."
