Quick to judge Macca. How do we know the person responsible isn’t a mentally ill spotty teenager born in Sydney. Of course the situation needs to be dealt with but I’m just making the point that there are a lot of assumptions made in your words, presumably because of a flag. It may turn out that the offender is indeed an islamic extremist, but when folk respond as you have it just feeds the monster. Irish advises ‘wait until we know’. I consider that to be excellent advice, particularly from someone who grew up in a place ripped apart by terrorism. I would add “Whatever the facts turn out to be don’t be tempted to turn against the innocent, even if they are different to us or wear different clothes”.
