Another terrorist who is a religious fraud. He was a drug addict with a criminal history.
Blaming immigrants (especially those from 30 years ago) is just ignoring we are all responsible for our own behaviour and actions. The vast majority of immigrants don't take drugs and screw their brains up to the point of hallucinating about spear people, don't get charged for speeding 47km over the limit, don't commit burglaries and violate court orders, and don't become ultra-religious (in this case Islamic) nutjobs who stab people.
Amazing courageous job by the cops by the way. The one that fired the shot was only 3 months out of academy. Held their nerve despite the threat to their own lives until the terrorist was in close range and open chested before shooting him to prevent any chance of a stray shot in a crowded area. A credit to their training, skills under pressure and obviously bravery.
