領事館保安人員可唔可以陀槍？

There should be US Marine (at least 7 persons are situated US Consulate General in HK) station inside every US Embassy worldwide, but they don't wear formal Marine Uniform. They are in either Casual or in Suit for handling the routine of the embassy. You cannot tell who is who.

Hong Kong's US ambassy they do have US Marine inside as the interior security force, I had seen them before !!!
