Tonight's ESPY Awards—ESPN's annual award show honoring excellence in professional sports—began with a speech from four NBA stars on racial injustice and police violence in America. 

Carmelo Anthony, Dwyane Wade, LeBron James and Chris Paul alluded to last week's events in Dallas—and to recent police killings of black men in Minnesota and Louisiana—to make a bold statement about America's tense race relations. Watch video of their joint speech above. 

The foursome also spoke about using their platforms as professional athletes to empower communities. They spoke of promoting justice, understanding and shared responsibility in rough times. "Racial profiling has to stop, but also the retaliation has to stop. Enough is enough," said Dwyane Wade. 

LeBron James echoed that point: "We all feel helpless and frustrated by the violence. We do. But that’s not acceptable. It’s time to look in the mirror and ask ourselves: What are we doing to create change?"
