From Breitbart:

The Statesman Journal reports that Prozanski pushed the measure in spite of the testimony against expanded background checks from law enforcement personnel like Grant County Sheriff Glenn Palmer. Palmer cited the the ineffectiveness of background checks to show that the passage of SB 941 is really just a way to get government more heavily involved in regulating the Second Amendment. He called it “borderline treasonous,” and said his sheriff’s department would not enforce it.

Oregon Sheriff says he won’t enforce new law:

Sheriff Daniel, who is the new top cop for Josephine County which shares a border with northern California, told reporters that believes this latest gun control law goes against his county’s charter. He also said his department doesn’t have a sufficient number of deputies to pursue lawbreakers who are committing a frivolous misdemeanor.
