While this may be true in an ideal world unfortunately there are 
scenarios that are somewhat reasonable for having them out of sync.
eg I have some photos sent to me by a friend that has some tags applied 
to it. I do not want to remove those tags nor do I wish to import them 
into my database but I do wish to add my own tags.
