"SHOW them graphic pictures, show them a dead body. Show them Brandon's if need be."
Matthew Matthews' words are chilling, but so is the story of how his little brother was murdered on the streets one night.
"Until someone is shown the impact one act of violence can have, it means nothing," he said.
"If it saves one person's life, it is worth it. It could even save mine."
Brandon Matthew's killer took more than one life during a street fight in Ipswich on January 7, 2012.
Zachary Michael Moloney tore a hole in the Matthews family. He will remain in prison until 2028.
"For a time I wanted to seek revenge, but it's not going to bring my brother back," Mr Matthews, 24, said.
"The only thing I can do is tell the story of what happened to my family and hope someone listens."
He is calling for all the political correctness to stop.
He believes in tougher penalties, inescapable advertising and added responsibility on those standing by.
"One punch should carry a charge of attempted murder," he said. "Everyone knows that is all it takes."
If there are idle spectators to an act of violence, videographers or people egging violence on, they too should be subject to the same penalties.
"Violence is senseless and it's selfish," Matthew said. "Our whole culture of drinking needs to change."
While Mr Matthews says he will never again know a normal life, it has enhanced his zest for life.
In 2015, he will depart for Canada for two years to realise his dream of seeing the world.
"Life is short. Brandon has taught me that now is the time to act on a lot of things," he said.
"Campaigning against violence is one. Surrounding myself with positive people who don't fight is another."
