Part of me wonders if perspectives on Sam have changed? Its very odd that Jamie files restraining orders against Sam that extend to Britney and her entire family, while the likes of Lynn are fighting him in court?
I do not believe for a second that he is a completely innocent person, but he was hanging around with Britney's manager for years after 2007 with other high profile clients.
I honestly believe that Sam knows too much right now. When the narrative that Britney needed the C-ship worked without a hitch, it was easier to keep him quiet, but now that so much has come to light, the only other person who was around Britney in 2007 and has been a reoccurring figure for years is Sam Lutfi. He was the reason that Jamie fought against giving Britney her legal notice for the initial hearings. If Britney confided in anyone at that time, it was more than likely him (whether it was because she was vulnerable or otherwise).
There's too much effort placed on keeping him out of the narrative.
