You come in with your preconceived point of view, which is fine.
You hadn’t bothered to educate yourself on the chains of transmission before the start of your accusations today. All of which has been on daily pressers, in all forms of news, even in this forum. People here have tried to bring you up to speed on what has happened while you weren’t paying attention.
You don’t understand what a contact tracer does, or how they operate, e.g. they found case 5 the same way they find most cases including asymptomatic ones, by the fact that they infect others, and some others are less selfish and get tested when they develop symptoms, then they are traced and tested as close contacts. Under interview, he then “came clean”. But Chop and others have patiently explained to you.
You don’t seem to seek to understand, but to blame, with a simplistic “pass” or “fail” judgement. At different times, different areas have been major contributors to a “fail”. In this particular lockdown, if you take the time to educate yourself, you’ll probably come to the same conclusion most (not everyone) in here has, that the major contributor was a few selfish individuals, who didn’t listen to the warnings that have been made abundantly clear. Their selfish acts created an outbreak with enough unknown transmissions for public health to be fearful of losing control without lockdown. They could have tried to contain it without lockdown, sure. But if it didn’t work, which was very likely in this case, we’d have been looking at months in lockdown again. Much as weeks of lockdown can be tough, months are harder. We know, because we endured them, and most Victorians, not all, prefer a known short lockdown to a possible very long lockdown. We’ve been on the wrong end of that equation before.
I have sympathy for Victorians who were living life to the full after previous lockdowns. But when you’re sick enough to see a doctor for your symptoms, it’s pretty hard to feel sorry for someone who then spent the best part of the next 2 weeks socialising all over Melbourne without ever bothering to get tested.
