As John Oliver said (I'm paraphrasing here), 'perhaps instead of just condemning any booing/chanting, we should ask why they felt the need to do so in the first place.'
Honestly, I have lived here for 18 years and was (clearly naively) gobsmacked at the unrelenting torrent of GRIEF AND SADNESS AND MOURNING that was practically mandated by every politician, journo, etc.
edit: and Graeme can kindly gtfo with those stupid comments.
