Have just watched the clip.
I think he did come across badly [looked arrogant and defensive] and they both seemed focused on alleviating any blame on them by continually stating they didn't expect it to go so far, prank calls are done every day, no-one could have anticipated this tragedy...
That said however I think their emotion was real and that they truly felt gutted and shocked - probably due to both their prank being the catalyst event which led someone to commit suicide and also the implosion of their careers...
However I also had the sense that they had been briefed and probably had a team of lawyers and producers breathing down their necks.
Tracey Grimshaw kept asking about filters and process and the pair kept stating their ignorance and obfuscating.
I felt this was disingenuous as it seems unbelievable that the pair would record something to go to air but truly had no idea, apparently, of who made the decisions re editing, etc.
I do though feel sorry for them because I think they are two young and generally glib radio DJs who are used to presenting a light entertainment yoof orientated show and have probably never thought through the consequences of their actions and behaviour before.
They have a producer and legal team to do this for them [no need to bother their pretty little heads with it].
The producer and legal team however do not have to face the media shitstorm while these two do.
It must be a very hard lesson to learn in accountability and humility in front of a hostile press and social media.
Before someone jumps in and says it, I do think you can have some sympathy for the DJs whilst also feeling desperately sorry for the poor nurse and her family.
One does not cancel out the other.
