evidence: When Bernard C. Parks, former chief of the Los Angeles Police Department, watched the videotape of Minneapolis officer Derek Chauvin kneeling on George Floyd’s neck, Parks noticed something that most people did not. As the world well knows, Chauvin and his partners forcibly confronted Floyd outside a convenience store on May 25. With his knee, Chauvin pinned Floyd to the ground. Floyd was face down. He gasped, and he begged Chauvin to let him up. Floyd pleaded: "I can’t breathe." Parks viewed the video with 37 years of experience as a police officer. He is African American and grew up in the LAPD. He became chief in 1997 and was elected to the Los Angeles City Council in 2002. Today, when some people respond to the indisputable observation that "Black lives matter" by insisting that "blue lives matter," Parks represents both viewpoints — and, as his life is testament, he is willing to air his views and unwilling to bend them to the desires of others. It is not surprising, then, that when Bernard Parks watched Chauvin press his blue knee into Floyd’s black neck, Parks noticed something telling.
