Staples, a refreshingly frank interview subject who rattles off his answers in a quickfire monotone, says everything he talks about on Summertime '06 really happened.
"To me, that's the story. It's the best version of my truth. I never wanted to get out of that lifestyle. There was nothing wrong with my upbringing. There was something wrong with the choices [that I made]," he says.
"I'm trying to do my best, tell an appropriate, accurate story, because there are people in that situation who need help getting out of it."
After years of braggadocio from MCs who may have not lived that life, Staples' stories could be considered hip-hop cliches.
But his upbringing - at one point, he raps: "I'm a gangster like my daddy" - means Staples' words carry plenty of weight.
And he has some harsh things to say about rappers who say the same things about drugs, crime and murder, but haven't lived that lifestyle.
"I think they're ignorant. There's nothing wrong with being creative [but] the thing we do in hip-hop is we try to pass off our word as if it's fact, all of the time," he says.
"I never listened to Eminem as if he really had his wife's body in the car. There was a playfulness, a certain tone to it. That line has been blurred over the years and it's not fair to the listener because when I was younger I know that stuff affected me and how I looked at the world.
"We need to be more responsible with our words."
Those words have been heeded. Summertime '06 was widely considered to be the second best rap album of 2015, just behind Kendrick Lamar's masterpiece To Pimp A Butterfly.
And while Staples no longer lives in Ramona Park, he visits regularly. And he's happy to report it's changed - for the better.
"There are police cameras that feed live to the station, so it's pretty quiet. Thank god a lot of younger kids aren't really starting to gang bang no more ... there are soccer games, a lot of kids running around."
Even so, Staples says his words are being heard in neighbourhoods that haven't seen that improvement.
"I've got friends in places like that who are never getting out, but they call me and say [the album] lifts up their spirits.
"That's definitely something I aimed for.
