When the parents of a Perth teenager buried their son in 1995, they said they hoped no other parents would have to go through their hell.
Shockingly, 16 years later, almost the exact thing happened in New Zealand.
Jeremy McLaughlin is to blame - but the New Zealand and AustralianGovernments need to take some responsibility also.
McLaughlin was convicted of killing Phillip Vidot in Australia after he bashed the teen with a cricket bat while his co-offender ran him over in a car. McLaughlin was sentenced to 12 years' jail for manslaughter. He served only four years before being deported to New Zealand in 2001.
In 2011, McLaughlin killed another teen, this time the daughter of his former partner. A jury last week found McLaughlin guilty of murder after he killed 13-year-old Jade Bayliss before setting fire to her house.
Thanks to New Zealand's legal system, the jury was not allowed to know of McLaughlin's previous teen killing. Imagine how those jury members would have felt after this was made public if they had delivered a not guilty verdict.
What is even more ridiculous is that Jade's mother, Tina, did not know about McLaughlin's past, despite approaching police with concerns about McLaughlin's odd behaviour days before Jade was killed.
Police have since said their hands were tied because under New Zealand law there are constraints on what police can disclose to other parties about a person's previous criminal history. What rubbish. If she was tapped on the shoulder and given a warning, Jade might be alive today.
At last Justice Minister Judith Collins has realised this law is a bit strange and has promised to take a look at it. But let's not stop there. There should be serious consideration given to allowing jurors to know relevant convictions for any accused.
The law needs to be changed. When you rent your house, you do background checks on prospective tenants, when you hire a babysitter you check references. People's backgrounds are entirely relevant.
The onus has always been on the Crown to prove someone is guilty but if you've got a dodgy past, surely it's up to you to prove to society you're a changed person. Maybe a law change will make people think twice about having a record.
