I saw this news item, too, and was quite amazed at the devious mind that came up with this law. Surely if anyone steals our car it is the theif who should have the law brought down upon them. To hold the person who's car MIGHT be stolen because the thief has a little more opportunity to break in, surely can't be just.
What if the car-thief admits to the police, when caught, that he got in easily because of a window being down. Does that bring the car owner and even bigger fine? This law is laughable - or would be, if the poor sod didn't have to pay a fine.
This law's a bit like saying because I forgot to lock my front door and a burglar came along, tried the door, found it unlocked and stole all my goods, it is my fault not the thief's. Get real!
You could take this law to ridiculous lengths. I didn't put my burglar alarm on so I should be prosecuted because it gives a burglar more opportunity to get away with a crime. Or, that garden gnome in the front garden. Better take it out or risk a fine. You could be tempting someone to use it as a bludgeon...
I recall years ago I'd leave all the windows of my old Holden down, right the way down, and go for a swim. My attitude was, "Well, if they need this old bomb that much, well welcome to it." It certainly kept the car cooler than having all the windows wound up.
What's with some of the so-called law makers? With "ignorance being no excuse of the law," it seems there is nothing that we can do that is not unlawful.
