I can understand the fear, but the mistake to begin with was Reagan recognizing INTERPOLas a Public Internatinoal Organization in the first place.
I would think, under Section 2(b) of the International Organization Immunities Act of 1945, Interpol would have been exept from FoIA anyway, not to mention they are not a an oganization under any State or Federaloperated organization.
If you ask me, Diplomatic Immunity should be stripped away anyway for any organization. And if other countries do the same to us, so be it. Diplomatic Immunity is a disgusting perversion of our laws and as if a citizen would be charged, tried, convicted, same for a normal foreginer. But diplomats, and even some of their staff are afforded some benefits of being immune from any kind of police action or prosecution. It wholly digusts me. But it was all likely done to give our own law enforcement more access in other countries.
I will say this though, even with Reagan's original order, no International Police Organization has jurisdiction in any state without going through that state's law enforcement agencies. I am pretty sure North Carolina operates like this as the FBI, BATFE, U.S. Marshal's, INS, etc, etc have little jurisdiction if any unless it is a situation where they have first jurisdiction (such as Federal property, etc). INTERPOL would, I am sure, have to get permission as well and would still have to work under the guise/umbrella of a local/state LEA.
I'll ask an authority on the matter to be sure of that.
