I assume HK reporters can do whatever they want, including taking pictures of you personally, your staff, or your office, company premises or company property (equipment). If that is not true, they can sure take pictures of your building from the outside, right? And if so, how about through windows?
My company has a client that is currently making some headlines overseas (nothing negative, on the contrary). Since they prefer to lay low, press showed up at our place claiming that our client sent them (which is not true). Sent them away, informed security, etc... they took pics from the street (don't ask me why and for what). We have CCTV installed and signs up that say no photo taking allowed etc in case that matters.
I gave them our company brochures, but I guess they are not interested in writing about us ;-)
Just wondering. My guess: they do whatever they want.
