A new article by Dr. Jennifer Roberts and fellows with the Harvard JPB Fellowship begins with a painful reminder: “‘I can’t breathe’ were the last words spoken by Eric Garner (July 17, 2014), Javier Ambler (March 28, 2019), Elijah McClain (August 30, 2019), Manuel Ellis (March 3, 2020), and George Floyd (May 25, 2020).” All were Black men killed by the police.
