Since April 2014 (v2.0), there are no friend permissions anymore and it´s not possible to get user data from people who don´t use the App. See the changelog for more information: https://developers.facebook.com/docs/apps/changelog
The docs are a bit misleading, you can only use /me to get data of the user who is logged in at the moment.
Update:
By requesting /me/friends, you get all the friends using the App. But as i said in my first sentence, there are no friend permissions anymore. You will only get ID and name of your friends, nothing else. Even if your friend authorized your App, you can ONLY get more data with his own session and by calling /me. The email permission only gives you access to the email of the user who is logged in, not access to the emails of all his friends, of course.
You can only store the email after authorizing a user, that is the only way for other users to get the email of his friends - at least the ones who authorized your App too.
