What do you mean snuck into the cottage early morning? He was there before he was at Port Arthur. He killed people. He was there afterwards, he shot and shot at people all the way up and from out the front.

They're all liars though. Everyone is lying because that's what you do when something like that happens. You lie about it.

To suggest that the people down there are covering this up is so impractical that you can't even explain it, not to mention absolutely disgusting. You have no reason for the cover up, you have no end game, all you can do is work backwards from your sick twisted conclusion that you want and pick pieces out of some tiny events in the middle somewhere. Like 'why did he buy a lighter when he didn't smoke??' 'Was he asleep when the place burnt down' -

You forget all practicality and just keep suggesting alternative far-fetched rubbish that 'could have been'. No matter how impossibly unlikely it is. You're sick.
