Public Facebook Wall Posts

Some facebook users have made their profiles public. You will have to download the walls (public status updates) on the profiles of users whose facebook walls are public. You will need to fetch all status posts by a used dating back to May 1st, 2011. You will need to download these wall posts for 50,000 public users. This is a slightly involved task, so please write to me and demonstrate that you understand how to do this. *Do Not send generic messages saying you are capable of doing this work*. We would like to see examples. Will need both source code and data. Any language is fine, but python is preferable. Thanks.
