I do know the answer, I've been a POLIS MPhil student, and the answer is you need to speak to POLIS. I've also been a member of staff and know more than most will know about the internal workings of CamSIS, and the answer is you need to speak to POLIS.
POLIS has always had students doing sensitive research re overseas political parties, corruption, conflict legitimacy and commercially sensitive matters. It has procedures, they are security procedures, they aren't discussed in public. The answer is you need to speak to POLIS.
Tina Liu, if you are doing genuinely politically sensitive research, then you ought to know by now how to go about managing security protocols. You need to speak to POLIS!
