Someone else's words can easily become somebody else's incentive. What if someone actually took it upon themselves to carry out such as attack? Who does the hammer land on then? The one who did it or the one who incited it?
At the end of the day, someone in his position using a service like twitter should have the bleeding common sense to realise posting such a stupidly agressive message is of course going to bite him on the arse. There's no real justification in his actions, and the argument that the Journo should have come back with a witty retort is only going to add more fuel to the fire.
Infringing on free speech isnt the issue. Its someone being a tool!
