Although the IC is committed to assisting law enforcement where it is legally proper to do so, it must also remain vigilant in protecting classified national security information from unauthorized disclosure. Just as with law enforcement agencies, the successful functioning of the IC turns in significant part upon the ability of its intelligence officers covertly to obtain information from human sources. In carrying out that task, the intelligence officers must, when necessary, be able to operate anonymously, that is, without their connection to an intelligence agency of the United States being known to the persons with whom they come in contact. For that reason, an intelligence agency is authorized under Executive Order 12958 to classify the true name of an intelligence officer.

During the pre-trial progression of an indicted case, as the court enters its CIPA rulings under sections 4 and 6, it may become apparent to the prosecutor that testimony may be required from an intelligence officer or other agency representative engaged in covert activity, either because the Court has ruled under CIPA that certain evidence is relevant and admissible in the defense case, or because such testimony is necessary in the government's rebuttal. Just as the substance of that testimony, to the extent it is classified and is being offered by the defense, must be the subject of CIPA determinations by the court, the prosecutor must also ensure that the same considerations are afforded to the true names of covert intelligence community personnel, if those true names are classified information. That is, the prosecutor must seek the court's approval, under either CIPA section 4 or section 6, of an alternative method to the witness' testimony in true name that will provide the defendant with the same ability that he would have otherwise had to impeach, or bolster, the credibility of that witness.

In any criminal case in which it becomes likely that an intelligence agency employee will testify, the Assistant United States Attorney (AUSA) assigned to the case shall immediately notify the Internal Security Section (ISS). That office, in consultation with the general counsel at the appropriate intelligence agency, will assist the AUSA during pretrial motion practice and litigation on the issue of whether the witness should testify in true name and other issues related to the testimony of intelligence agency personnel.

this part stuck out to me Q are you going to declassify
