News items per album group

So close to what I want to achieve... :-)
I currently have family groups that mandate when someone can see an album. The albums are unpublished and the users do not have editing rights. This way family members only see the album of their family. When it comes to news I saw you can do the same thing with categories. But I cannot seem to get the users to only have read only rights for news. They have full editing rights for news. Is there a way or small tweak I can do to prevent the user to see the whole editing field in the admin menu? As always, thank you so much for your great support!
