SUE Mill knows exactly what she believes should happen to Armstrong Renata and Daniel Maxwell if they are convicted of killing Cole Miller.
Lock them up for life.
The Currimundi woman lost her 22-year-old son Josh after he was punched in the head and bashed at a Caloundra taxi rank in November 2009.
She is angry so little appears to have changed since then, despite media campaigns and government crackdowns.
"It's terrible, it's disgusting and it makes me really angry," Mrs Mill said.
"The message is not getting through and I don't think it will until there are harsher penalties.
"They brought in new laws that say life in jail if convicted of it. Well do it.
"If they are found guilty, send them to jail for life.
"Make an example of them to the full extent of the law."
Mrs Mill has been an ardent campaigner against "coward punches" since her son's death.
But she believes education is not working.
"It seems that age group isn't getting the message.
"Maybe it will be better with the younger ones coming through school.
"The judges have to be stronger. They have to put people in jail and leave them there."
Queensland Law Society president Bill Potts agrees the system isn't working but says harsher penalties are not the answer.
He has urged the State Government to carefully consider lock-out legislation currently before it "in order to prevent the further loss of lives due to coward punches and alcohol-fuelled violence".
"I firmly believe in prevention rather than punishment," Mr Potts said.
"We must do everything we can to prevent the loss of lives, rather than focusing on society's retribution after someone is killed.
"Experience from other Australian states shows that lock-outs substantially reduce the rates of assault and can be an effective part of the solution to prevent more tragedies."
