In the UK, the police and prosecutors tend to take a common-sense approach: the "rebel tech savvy teen" would be the one who ended up prosecuted for possession.

In the UK, the police and prosecutors tend to take a common-sense approach: the "rebel tech savvy teen" would be the one who ended up prosecuted for possession. (Similarly: possession of an unlicensed gun carries a stiff prison sentence. But if someone chucks a pistol on your lawn and you without delay call the police and ask them to take it away, you're probably safe. Picking it up and taking it inside is another matter, however ...) The USA is a bit different. District Attorneys being elected means they have an incentive to bring charges against "soft" targets who'll take a plea bargain, i.e. hapless teens and people too poor to afford a decent defense lawyer.
