RIP to all those so senselessly murdered. Must be one of the worst, most horrific mass murders ever committed anywhere. To kill 23 sleeping infants with a knife is beyond comprehension. Yabba is a very insidious drug which makes people mentally unstable,delusional and often violent.. No doubt it will have an affect on the current debate on the acceptance or not of the cannabis laws being changed. Unfortunately although cannabis has not been shown to make people violent this case will likely be a factor in the new cannabis law being thrown out. Was also very disappointing to see some relatives of those murdered being asked to hold up big cardboard cut out cheques of money given to them by the government. Not a time for political point scoring.
