Denny Peyman didn't watch President Barack Obama's gun-control announcement Wednesday. But the Jackson County, Ky., sheriff said he already knows how the proposals will affect the way he does his job: not one whit.

Peyman is one of several sheriffs across the country who are vowing not to enforce new firearms restrictions that could be imposed by Congress or by executive order.

"Kentucky is a sovereign state," Peyman told NBC News. "The federal government is coming in and saying, 'This is what you're going to do.' We're not going to do it."
