For all we know...
the BBC may have posted the images on Facebook in the first place - wouldn't be the first time they attempt to make news rather than report it (just connected Saville's old work computer).
Whilst not a fan of the anti-social FB this is another example of the lack of self-awareness over the BBC's own actions (just like taking helicopters to Cliff Richard's house).
Will no one rid us (Licence fee payers) of this troublesome broadcaster?
