This designation is not intended to abridge in any respect the privileges, exemptions or immunities which such organization may have acquired or may acquire by international agreement or by Congressional action.
This simply says that the Executive Order does not abridge any other privileges INTERPOL may or may yet have.
Abridge is defined as follows:
1. to shorten by omissions while retaining the basic contents: to abridge a reference book.
2. to reduce or lessen in duration, scope, authority, etc.; diminish; curtail: to abridge a visit; to abridge one's freedom.
3. to deprive; cut off.
In other words, the privileges and immunities INTERPOL has obtained cannot be reduced/lessened/deprived/etc. This statement does not say the Constitution is king, nor does it say Congress can remove the Immunities provided for in the International Organizations Immunity Act.
NOW. That being said. Section 1 of the same act says: "[...]
The President shall be authorized, if in his judgment such action should be justified by reason of the abuse by an international organization or its officers and employees of the privileges, exemptions, and immunities herein provided or for any other reason, at any time to revoke the designation of any international organization under this section, whereupon the international organization in question shall cease to be classed as an international organization for the purposes of this title."
i.e. The President can refute these immunities at any time.
So as long as our President isn't a fucking tard, we have an escape hatch for this one... I'll leave you to decide whether our President is or is not a fucking tard.
Also, before people fly into a panic about INTERPOL and their newfound powers, it would be worth looking into what INTERPOL is exactly and how they operate.
This is from INTERPOL's own website:
http://www.interpol.int/public/icpo/default.asp
"
INTERPOL is the worlds largest international police organization, with 188 member countries. Created in 1923, it facilitates cross-border police co-operation, and supports and assists all organizations, authorities and services whose mission is to prevent or combat international crime.
INTERPOL aims to facilitate international police co-operation even where diplomatic relations do not exist between particular countries. Action is taken within the limits of existing laws in different countries and in the spirit of the Universal Declaration of Human Rights. INTERPOLs constitution prohibits any intervention or activities of a political, military, religious or racial character.'"
From Wikipedia's entry on INTERPOL:
http://en.wikipedia.org/wiki/Interpol#Methodology
"
Interpol maintains a large database charting unsolved crimes and both convicted and alleged criminals. At any time, a member nation has access to specific sections of the database and its police forces are encouraged to check information held by Interpol whenever a major crime is committed. The rationale behind this is that drug traffickers and similar criminals have international ties, and so it is likely that crimes extend beyond political boundaries."
So I don't think there is any imminent danger from this. That being said, I do recognize the potential for misuse and abuse this kind of action could lead to. And that
does worry me.
