Mark Zuckerberg is calling for criminal justice reform after visiting California’s San Quentin State Prison this week.
“We can’t jail our way to a just society, and our current system isn’t working,” Zuckerberg wrote in a Facebook post Tuesday, saying that U.S. jails hold about 2.4 million people, roughly 25 percent of the world’s prisoners.
Zuckerberg and his wife Priscilla Chan visited San Quentin after Zuckerberg read a book on the rise of mass incarceration and the disproportionate racial impacts of the system. Zuckerberg said they “wanted to see first hand what prison conditions are like for people,” and got to attend a coding class offered to the inmates.
“I was impressed by their spirit to return to their communities and provide for their families,” Zuckerberg said of the students, “as well as the dedication of the staff to help them reclaim their lives.”
Zuckerberg’s post doesn’t offer any policy suggestions, but in true Zuckerberg fashion he does say, “I’m going to keep learning about this topic.”
