YOUNG party goers had been making a racket in Girrawheen for more than 12 hours when nearby resident Aaron David Blastock decided his samurai sword might quieten them down – at 4am.
The desperate measure cost Blastock a $600 fine in Joondalup Magistrates Court on Friday after he pleaded guilty to carrying an article with intent to cause fear.
The court heard Blastock (37) asked the revellers multiple times to turn the music down but they ignored his requests as they partied on January 14.
The police prosecutor said the youths became aggressive about 4am when Blastock demanded they put a stop to the noise.
A group of them backed Blastock and his father back into their house.
The party had begun about 2pm the previous day.
Blastock returned outside wielding the weapon – an act that would later have him charged by police.
The duty lawyer representing Blastock said he acknowledged what he did was wrong and expressed remorse.
The police prosecutor was somewhat sympathetic to his situation but emphasised he took it a step too far.
“If he had got anything other than a samurai sword he probably would have been justified because he felt threatened,” she said.
In handing down the penalty, Magistrate Gregory Smith highlighted the risk of Blastock introducing a dangerous weapon into a volatile situation.
He said he should not have had the controlled weapon at his home in the first place, even if it was for ornamental purposes.
“What you should have done was gone inside and locked the door,” he said.
He said he should have let the police handle it.
Mr Smith ordered destruction of the sword.
