'I've never worked with blatantly racist cops'

The president of the American Police Foundation said he has "never worked with cops with a blatant racial bias" in his 33 years in the Southern California police force.

Reacting to the Dallas attack, Chief Jim Bueermann said "human beings have implicit biases" and training to deal with those biases needs to "be taken to scale in the United States and wrapped around the entire culture of policing".
