No double standards, basic LAW 101
No, there isn't a double standard, it's basic law and something this simple is high-school level.
Simply: If you find something in the street, hand it in to the Police. Obvious 20c is not going to attract attention, but I think for Australia (legal persons might correct me here...) the law states anything above the value of about $20. or is it $50? ANYWAY, you Hand It In.
The Police take your details, where you found it, and if no-one claims it in 6 months, IT'S YOURS. The "State", "Federation", "Republic" or whatever your local brand of Eeeeevil Empire(tm) is called, will only sell unclaimed items.
Two cases in point: 1. a friend found a camera bag with selection of lenses, SLR etc. Obviously lost or stolen, hands it in to cops. 6 months later, gets a phone call saying 'come get your camera' SCORE!
2. Bloke who works for bank (and should know better) finds a garbage bag with $1,000,000 in small loose notes. He hides it under his desk, at work (not very bright is he?). Sure enough, someone spots him taking large wads of cash from bag under desk, IN A BANK, so rightly calls security, who call cops. His story comes out, and is actually true - the bag was likely dropped in a drug deal gone wrong, BUT the prosecution pushes the fact that as bank staff he should have known better. Sentence - 2 years in the big house. Goodbye career in bank! Funny thing - if he handed it in, in 6 months he would have been a millionaire, what drug dealer is going to go and ask for his cash back? The money by the way, went to charity, not state coffers either.
As for these Gizmodo gits, hope they get the book thrown at them, or someone nicks their car "It was just sitting there in the street, obviously you didn't want it, so I took it and stripped it of parts!"
