""Because it has failed to do so — most fundamentally, because it has not shown it is vindicating an interest that is specific to the state itself — I find the State of Oregon lacks standing here and therefore deny its request for a temporary restraining order," he concluded."
"While I respect Judge Mosman," she added, "I would ask this question: If the state of Oregon does not have standing to prevent this unconstitutional conduct by unidentified federal agents running roughshod over her citizens, who does? Individuals mistreated by these federal agents can sue for damages, but they can't get a judge to restrain this unlawful conduct more generally. Today's ruling suggests that there may be no recourse on behalf of our state, and if so that is extremely troubling."
I thought states had jurisdiction over policing in their state.
Not over federal agents. Same reason why Arkansas couldn't prevent the Eisenhower administration from using US Marshals to enforce desegregation in Little Rock in 1957. (Or Army paratroopers, as per the Insurrection Act of 1807.)
