On July 16, 1986 he sent a letter defending CSIS from Royal Canadian Mounted Police allegations that they had been un-cooperative and negligent in tracing the suspects prior to the bombing.[1]
He retired from CSIS in 1994, but was called to testify before the Air India Inquiry - where he stated there was "no deliberate attempt to suppress evidence" relating to the recorded audiotapes that were erased by CSIS.[2]
