title: Facebook FQL app access token needs permissions to access public data?
body: <p>Using <a href="https://github.com/criso/fbgraph" rel="nofollow">fbgraph</a>, I authenticate a local script and retrieve an app access token, which I then use to perform this query:</p>
  
  <pre><code>SELECT post_id, message, share_count, comment_info, like_info, created_time
  FROM stream
  WHERE source_id = USER_ID
  AND actor_id = USER_ID
  </code></pre>
  
  <p>The user in question is a public page, specifically Oreo. Visiting their page takes no permissions, but this query using my app access token yields nothing. Specifically, this:</p>
  
  <pre><code>{ data: [] }
  </code></pre>
  
  <p>Do I need permissions to view public data? If so, how do I get them for the app without implementing a user authentication flow?</p>
