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.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4074614/mark-zuckerberg-criminal-justice-reform/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4074614/mark-zuckerberg-criminal-justice-reform/"},"headline":"Mark Zuckerberg Calls for Justice Reform After Visiting Prison","datePublished":"2015-10-15T11:25:16.000Z","dateModified":"2026-04-13T08:06:47.823Z","description":"He also visited a prison coding class","url":"https://time.com/4074614/mark-zuckerberg-criminal-justice-reform/","keywords":["Tech","Law","Criminal Justice","Mark Zuckerberg"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltbd1ae7cbe2279e49/69886859a988ca46736b4cf9/mark-zuckerberg-facebook1.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Tessa Berenson","jobTitle":null,"url":"https://time.com/author/tessa-berenson/"}],"articleSection":"Business","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltbd1ae7cbe2279e49/69886859a988ca46736b4cf9/mark-zuckerberg-facebook1.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Mark Zuckerberg at the F8 summit in San Francisco on March 25, 2015.","caption":"Mark Zuckerberg at the F8 summit in San Francisco on March 25, 2015.","creditText":"Josh Edelson—AFP/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/business/","name":"Business"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/time-section-tech/","name":"Tech"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4074614/mark-zuckerberg-criminal-justice-reform/","name":"Mark Zuckerberg Calls for Justice Reform After Visiting Prison"}}]}] ```
