A man who was left a paraplegic and partially blind after police shot him during a siege is reminded every day about his crime and should be spared jail, his lawyer says.
Daniel John Ashley, 27, burst into his ex-girlfriend's Perth home in June last year, armed with weapons including a replica gun and baton, taking her and four other people hostage for three hours before he was shot twice.
While Ashley's actions seemed frightening, terrorising and unpredictable, he could not actually have shot anyone, defence counsel Linda Black told the West Australian District Court on Friday
"Mr Ashley did not go out that night to cause harm to anyone except himself," she said.
"Every day that Mr Ashley wakes up he is being punished for what he did that night.
"There will be never a moment in Mr Ashley's life when he won't be physically and emotionally reminded."
The court heard a psychiatrist found Ashley to have an egocentric interpersonal style and difficulty relating to others.
Judge Simon Stone was not convinced Ashley had a depressive illness at the time of the siege and decided to delay sentencing to learn more from experts.
At an earlier sentencing hearing this week, Ms Black queried whether the prison system could care for Ashley given his specific needs, but the court heard on Friday that it was possible with extra staff.
Ms Black asked Judge Stone to consider a suspended prison sentence on the basis that imprisonment would be harder for Ashley than the average person.
Ashley has pleaded guilty to eight charges including being armed in a way that may cause fear, aggravated assault, aggravated burglary and five counts of kidnapping.
While inside the house, Ashley posted on Facebook: "Tonight, I'm going to die. I will be shot by police".
When he emerged from the Mosman Park house, Ashley ignored repeated calls to drop his weapon, which at the time was thought to be a gun, and was shot once in the torso before falling to the ground.
He then pointed his weapon at officers who shot him in the face.
Ashley has been remanded in custody to appear back in court on September 1.
