In the wake of an increasing number of police killings, more and more celebrities are speaking out. Serena Williams is the latest A-lister to take a stand against police violence, and like many others, she's using social media to do it.
The tennis superstar wrote in a heart-wrenching Facebook post yesterday that she was inspired to speak out while riding in the car with her 18-year-old nephew behind the wheel.
"In the distance I saw cop on the side of the road," Serena wrote. "I quickly checked to see if he was obliging by the speed limit. Then I remembered that horrible video of the woman in the car when a cop shot her boyfriend. All of this went through my mind in a matter of seconds. I even regretted not driving myself. I would never forgive myself if something happened to my nephew. He's so innocent. So were all 'the others.'"
Serena went on to say that she had to think about whether or not she'd been using her own voice to speak up.
"I had to take a look at me," she wrote. "What about my nephews? What if I have a son and what about my daughters? As Dr. Martin Luther King said, 'There comes a time when silence is betrayal.' I won't be silent."
