I am not saying that they're hack journalists because they literally accused Tan of incitement to violence (that would probably be libel). I'm saying they're hacks because the article (and the prior one) were full of irrelevant details about Tan, while ignoring nearly all of the details about the actual incident. Tan is not the core of the story, unless you've lost all perspective on your job as a journalist.
It's like reporting on a robbery, but making most of your article about Karl Marx because the criminal was reading a copy of Das Kapital. The only way you get to that point is to blame Marx for the actions of the criminal.
Some unhinged person sent a threat of violence to politicians, using Tan's tweet. That is the story. Tan's liquor cabinet, his history of political donations, his wealth...all of that is irrelevant.
