Oh well, think of it like this.
If I said "Some Journalist odd to be beheaded." Over on national television.
Tomorrow, you beheaded, say Ayaz Amir (The only Pakistani Journo I know) and now you said I incite you to behead Ayaz Amir.
Problem is, you cannot proof, beyond reasonable doubt that this is my decision, not yours, to kill Ayaz Amir, I said, "some Journalist", the board definition of "some" means not all, or not particularly whoever in mind, and this is your sole interpretation to choose Ayaz Amir for the beheading, I can put up a defence and say I did not tell you to kill him, that means the only thing that anyone can proof is your guilty mind to kill Ayaz Amir, because he is now dead.
You also cannot proof beyond reasonable doubt that I have malice, I did not tell you, teach you, or instruct you how to kill him in my original sentence, hence whatever ways, form and method you choose is yours to choose.
And finally, you cannot proof, beyond reasonable doubt, that I have motive to incite your killing, I may have no beef with Ayaz Amir, which make the decision to kill him your own.
Hence, without malice, motive and means, you cannot charge me inciting violence.
This is how court works...
