From Oathkeepers:

In this video, Oathkeeper151, a New Jersey Police Officer who has been a member of Oath Keepers since 2009, makes it clear that he will not obey orders that violate the Bill of Rights. In particular, he says he will not be used as a tool of oppression against the American people who resist and refuse to comply with infringement on their right to bear arms, such as legislation or executive orders that decree they must register, get finger printed and photographed, like a criminal.

He asks his fellow officers what they are going to do if that happens. Will they keep their oaths?”
