When I requested information from BCSC under their Freedom of Information act, they responded by asking me if I could narrow down my search request as there could be several thousand files on SLI. So I asked for any information pertaining to the RCMP investigation and anything regarding the missing azimuths. When they responded 30 days later with the information I was seeking, they informed me that out of the 29 records on file that they were withholding 14 of them:

We are withholding 14 records pursuant to section 16 [Disclosure harmful to intergovernmental relations or negotiations] and section 22 [Disclosure harmful to personal privacy] of FIPPA.
