beat, my encouragement to the state is look at the hope, look at what we can do when we come together, feed on that hope, because my strong sense is we're going to come out of it stronger. so i thank you to everyone who has participated. i know the city, i know the state is getting a lot of comfort from it. it is an incredibly symbolic gesture that is holding us high while we deal with these circumstances . okay, are there some questions? >> prime minister, you mentioned that this man had a long history of being known to police. what would you say as to how this was allowed to happen? >> that's a very fair question. and after the initial shock has passed that's precisely the question members of the public are entitled to ask. and if i can be candid with you, that was the question we were asking ourselves around the national security committee of the cabinet today.
