Following the execution-style shooting of Texas Sheriff's Deputy Darren Goforth on Friday, Harris County Sheriff Ron Hickman had strong words for the Black Lives Matter movement.

“We’ve heard black lives matter, all lives matter... well, cops’ lives matter, too. So why don’t we just drop the qualifier and just say 'lives matter,'” Hickman said.

Former Boston Police Chief Daniel Linskey said on "America's Newsroom" that when anti-cop rhetoric gets out of control, it has consequences.

"This wasn't an attack on Deputy Goforth. This was an attack on American society," Linskey said. "When you come after a police officer - not because he catches you and you're trying to escape from a criminal act - you come after a police officer and you assassinate him, merely because of the uniform he wears and the badge he wears, that's an attack on our society, and it's unconscionable."

Linskey called for the leaders of the Black Lives Matter movement to stand up and declare that violence against police officers is not what they represent.

"Those who are trying to coopt that movement and talk about assassination of police officers, it's disgusting, it's outrageous and they ought to be ostracized."
