Fetching the public status messages of users on Facebook, in a certain area, without logging in

I am coding a facebook app which aims to fetch all the public status messages/checkin places of users falling in a particular range/area. I can provide facebook with latitude-longitude pair, a range and expect it to return status messages of people in the area matching the latitude-longitude pair and the range.

Is it possible through Graph-API or FQL? I can consider both.

till now I have zeroed my search on facebook 'search' API, but am not sure whether it does the above thi开发者_如何学JAVAngs.

One more thing I am worried about is the need of logging in. I want to search the things which are publicly available, while my users don't have to log in to their facebook accounts.

I searched Google with few keywords to see what kind of data facebook makes available to third parties publicly, and I can only get results of pages and groups.

Can't I get Users's messages publicly!?

Found out that Facebook won't let me pull data publicly, at least as of now, and will require users to sign in and provide specific permissions, which I have specified, to my app.
