Law in Australia suggests I can be charged with 'theft by finding' if I don't make a reasonable attempt to identify the owner.
Wow, that's one hell of a law--in a silly, brainless way I mean. I'm not dissing Australia, mind you, because there are just too many laws worldwide and way too many that don't make sense.
We have similar laws: it just means that when you find something, it's not automatically yours. I think there's a 1 year time limit here for the owner to report.
