"I was very clear: It's not an anti-police thing. In fact, the police are a key part of the solution in this issue," Jenkins said after practice Saturday . "It has nothing to do with the military, nothing to do with the flag itself. If you listen, the message has been the same across the board. The police are a key part of the solution, in this issue, across the nation."
Jenkins, a Pro Bowl safety last season, said the team didn't protest before the season opener last week out of respect because it was 9/11. He said he's spoken to 49ers backup quarterback Colin Kaepernick and told him he's proud of him.

"Whenever you're trying to change something, there's no comfortable way to change it," Jenkins said. "If somebody gets upset, then it's probably because they're not listening."
