I wonder if reading articles and looking for follow up articles ever struck posters here as a good idea.
A couple of points...
Firstly, the "kid" has since been charged and will face juvenile court... I guess that means he was let go into his mother's custody (rightly or wrongly).
The "kid" was not forthcoming with information, nor was he in company with a responsible adult - hence hand cuffs in the first place - considering the implications of his crime.
I also find it quite ironic that a select few managed to pick up on the Child and his Mother being Aboriginal in a flash yet completely failed to notice one of the arresting officers being Aboriginal... Which effectively flushes your blatant racist crap down the toilet, except I suspect those with said tendencies will lack the honesty, self reflection, integrity and brains to acknowledge having gone off half cocked...
The kid is a brat, he has been charged and, arguably, his mother should have a few reports to child protection agencies done, that said, I would not be at all surprised if there are existing reports already in the system.
In short, storm meet tea cup.
