"I say this respectfully to the CDC but we really need to get back to a point where it's encouraging (people) to get vaccinated and more of that focus rather than celebrating our newfound freedoms," the mayor of Kansas City, Missouri, told CNN on Monday. "Because the honor system just ain't working here, I don't think it's going to work in a lot of parts in this country," Mayor Quinton Lucas said. Now, the mayor said, local officials are worried about how to move forward. "It creates these sort of challenges where, how does the store clerk check it? How does our health department actually enforce any rule at all? So, while I respect many of the jurisdictions that are trying to, I think, really have adherence to the CDC (guidance), it's a challenge for us," the mayor said.
