Australia Un-Democratic on Death Penalty

Australia has abolished the death penalty, and in all cases this was done without referendum. An article suggests that it would be reintroduced if a referendum was conducted, but the writer of this article 'fears' referendums. Sounds like the left wing establishment prefer an authoritarian dictatorship, where people have no say and no justice.
My argument for the death penalty is this.
In Western Australia 2 murders (1 Chinese female student in Innaloo 2007, and 1 Japanese Australian Permanent Resident at the Wellington St Bus Station, Perth 2007) were carried out within 3 months of each other, with one murderers just released from prison and the other on bail for another offence. The Government bureaucrats have told me directly they like to let them out so they can 'watch them'. This is Labor's mind-numbing policy on 'justice'.
So if we had the death penalty, and these 2 were either on death row, or deceased, the state's murder rate would be reduced.
And, if we had built a massive prison instead of a new 2 Billion dollar Urban Railway to Mandurah, we would probably be keeping these criminals in jail (if Labor actually supported keeping them in jail-which I am sure they have little interest in doing).
All in all a lot of crime is caused by the early release policy of Labor and most importantly Labor is exposing the community to grave risk.
The least Labor can do is advise the community that they have released dangerous offenders onto the streets. At least we will be more aware of who is actually in the community, and not in jail........
Labor (all states in Australia) has done this famously with paedophiles and caused major protests from each community where it has been revealed across Australia that these child abusers are out and ready to play with your kids!
The left famously use the 'innocent' argument against the death penalty and it has worked for so long. As long as we are scared of innocent people being put to death for murder, we will see more of the above until we actually fess up to our softness and get on with the job of necking a few bad guys who especially ARE the culprits.
