Well if not reported stolen you may well be right police should not have taken it
However there may well be some thing we are not being told

Jackofharrassment,
Which police station ? What vehicle? What date towed?
OLO is on the case , police are on the run , we always get our man .

Hi Jackofharassment,

I don't know, I suppose it depends if you lie and call one thing something else, like this:

Call it 'Sacrifice' and they get to go free.
Everything's in today's society is upside down or back to front.
Looks like 'Murder' and 'Conspiracy to Murder' to me, but what do I know?

Maybe you could argue that the Police themselves stole your car?
- It makes about as much sense as anything, these days...

"Police sources also said the mother had been released from custody and it was understood she had been placed in the mental health system in Queensland."

The man is placed in the police stolen car with healthy mental state of NSW , sacrificing his drinking mates who stole a police station and drove it to Port Morseby.

AC, I still go with my suggestion of outstanding warrants.ie; unpaid parking, speeding fines or fines in general, if the scumbags have succeeded in getting on the cops FU2 list they send them your cars rego, and hey presto your stuffed.
For example, in some states, if you don't pay a parking fine the bastards give your car rego# to the cops and you don't get your renewal for that year.
If your on top of your paperwork you will realise it and when you ring up to abuse them for not sending the renewal you are faced with this arrogant, holier than thou scumbag telling you that you are in breach and you can't renew your car rego until you pay the fine.
Just another angle.

"Hey scumbag where's my rego , I put 2000 Chinese in the CBA hot-deposit , you slime".
" You greasy rat dropping , that was fake Mickey Mouse , we do Crown Casino chips you drop kick"
"So what's your problem, dung face?"
" Morons like you don't pay fed tickets do yer , reject".
"I'll pay when you do my rego , or you're dead meat".
"Yeah"
"yeah".
