More than 2,000 people gathered to remember the life and legacy of Mack with a funeral service that began at 11 a.m. at the West Angeles Church of God in Christ on Crenshaw Boulevard.
Prominent city officials who spoke at the funeral include retired LAPD Chief Charlie Beck, LAPD Chief Michel Moore and L.A. Mayor Eric Garcetti. Retired NBA player and president of basketball operations of the L.A. Lakers Magic Johnson also delivered a tribute to the late civic leader.
"Activism on the streets is always where things start, but there are few activists who will have the courage sometimes to cross that street, to, yes, build the coalition but also to lead the commission," shared Garcetti.
Mack died of cancer on June 21 at Cedars-Sinai Medical Center. He was remembered as a man of great strength.
"He worked tirelessly. I call him our modern-day Hamilton. He wrote and wrote and always was there for the community," said Pat Harris of the Urban League.
Mack's grandchildren talked about how his life affected them and so many in L.A. He was one of the city's most influential leaders during some very tumultuous years.
