On July 17, 2014, Carr's son Eric Garner was killed by a New York Police Department officer who used a prohibited chokehold while arresting Garner. Garner's death was filmed, with "I can't breathe" being his final words, which went viral and became a mantra of the Black Lives Matter ("BLM") and anti-police brutality movement. Carr became part of the BLM movement and became a leading supporter of justice for the death of her son. On December 4, 2014, a grand jury declined to indict the police officer, Daniel Pantaleo. Carr expressed disappointment and frustration at the decision.[2]
Carr is a critic of New York City Mayor Bill de Blasio, who in 2016 opposed a bill that would have banned police officers from using chokeholds. Carr did not vote for de Blasio in the 2017 election.[6] She endorsed Hillary Clinton in her 2016 run for president.[7]
After the videotaped murder of George Floyd, choked by Minneapolis police in May 2020, Carr immediately contacted and consoled Floyd's family. Just like her son, Floyd's last words were "I can't breathe." After her first conversation with the Floyd family, she told them: "Don't forget. You cannot let this go."[3][9]
Carr spoke at protests in Queens, New York and Staten Island, followed by attending Floyd's memorial service in Minneapolis and Floyd's funeral in Houston.[10][11]
