Ever since Colin Kaepernick started his protest against racial inequality back in August, dozens of NFL players have joined his cause.

One of those players, Doug Baldwin, has been so serious about making change happen that he actually made a proposal calling for all 50 states to review their police training policies.

Unfortunately for Baldwin, it appears that not everyone is on board with his idea. In the eight days since making that proposal, the Seahawks receiver told 60 Minutes Sports that he's received several death threats.

"I had a few," Baldwin said. "A couple of people told me to watch my back."

Kaepernick has also been receiving death threats. So far, both players have had the same response: If something happens to us, that will just prove the point of our protest.

"You know, there's issues going on in our society that people feel compelled to talk about and I'm not going to be quiet about it," Baldwin said. "And if something was to happen to me, I think that would just further prove the point that there are issues in our culture, in our society that need to be changed."

Baldwin, who's the son of a police officer, said on Sept. 23 that he'd like to see every state in the country review their police training policies.

"As an American, a black male in this country, I'm suggesting, calling -- I'm demanding that all 50 state attorney generals call for a review of their policies and training policies for police and law enforcement to eliminate militaristic cultures while putting a higher emphasis on de-escalation tactics and crisis management measures," Baldwin said.

Baldwin will be featured on Tuesday's episode of 60 Minutes Sports, which will air at 8 p.m. ET on Showtime. You can see a clip of Baldwin's interview below.
