Someone said :
They are of course not trying to incite violence, but they are channelling the anger and frustration that exists out there in the populace. Besides, its a commonly used phrase where the user doesnt usually mean what he says. Ive noticed how the Star can sometimes be the bravest and most forthright on issues when other papers just skirt around and dont capture popular sentiment enough
On the face of it, inciting violence is exactly what they are doing! Notice that the headline is not encapsulated in scare-quotes, the usual tactic used by papers when they want to stir things up but need the defence of quoting someone else in the 'public interest'.
I appreciate that the phrase is commonly used as mere abuse, but the context here is ambiguous, to say the least. You could argue it either way ultimately.
Also, the headline isn't simply capturing or reflecting public opinion, it is amplifying a certain section of public opinion.
I think it is over the top sensationalism, trying to bag a few extra sales on the back of public outrage.
