On Tuesday night, while having dinner with some friends, I received two almost simultaneous text messages. The content: the White House had listed a series of what it called under-reported terrorist attacks around the world, including the Parramatta shooting in 2015.

It was so ridiculous that I could only describe it as befuddling.

Dad's shooting outside the Parramatta Headquarters was a tragedy. It was clearly reported. I know, because I followed and read many of the stories and articles in the 18 months since.

I know it was reported around the world because I received messages of condolences from around the world: the UK, Hong Kong, Israel, France, Russia and the US, to name a few.
