First, I only feel sorry for the family.
Apparently, these 2 guys have done it before.
I guess AFP had enough of prosecuting criminals in Australia, spending time, effort and money (cost to us tax payer) with government provided lawyers, court, judge, multiple appeals then the punishment probably is light then they back on the street and not repentant then most probably do the same thing, its a cycle, costing the country lots of money and maybe for little positive return. The cost just add on when there are 9 of them. The last I heard, it cost us $70k plus a year to have someone kept in jail.
Now they may seem repentant given the death sentence, but only they themselves know if they have change in their hearts and mind.
Hanging, shooting or injection sounds barbaric in
the 21st century.
