The biggest voice of reason in this was a flash to CNN at 43:50 in the video, when Anderson Cooper was reporting about her, then it flashes to Larry King who had Michael Moore by his side, and Moore just says something like "Why don't we all just leave her alone?" with a face that clearly thinks this is not real news. This is not long after Perez Hilton is shown gleefully saying "Thank you Britney, being bad is so good for my business". Fuck off!
Anyway, her situation as a huge celebrity being hounded and mocked is rare on that scale but not unique, however the conservatorship certainly is and that's the most interesting part.
