" 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?"
UMMMM HELLO?!?!?! The state of Oregon has the ability to stop this in its tracks by PREVENTING THEIR CITIZENS from running roughshod over the law. They can stop their vandalism and arson as well as their terrorism and acts against the United States Federal Property and employees!! Do your damn job Oregon PD, Mayor and Governor! Do your job and the Feds will stand down.
If Federal police cannot operate within the 50 states, where can they operate?
