Here be the interview clip in question.
From about four mins onwards, KGM makes several attempts to peck away at Tarantino, trying to draw him out re: the perceived link between movie violence and real life violence. Even saying at one point [6.00 mins-ish] that 'today' the [US] 'Vice President is talking to people in the movie industry' about the alleged link between the two. OK, KGM didn't utter the precise words Sandy Hook
, but he sure as hell wasn't alluding to the US Fiscal Cliff crisis. QT appeared to be fully aware of where KGM was 'going', so 'shut him down'. QED. x *goes off to find phone box for this week's meeting of the Quentin Tarantino non-appreciation society*
