Good luck proving it!

In a country where possession of chewing gum is illegal and 14 grams of heroin geets you a death sentence, I'm not sure I'd want to test the practical limitations of the burden of proof on that sort of thing.

probably easiest to buy a second hand laptop, do the thing and then low level format the disk with a hammer.

But you already committed the crime, surely that alone will be much worse than a completely unprovable charge of destruction of evidence.

Some legal systems permit inference of guilt ("spoliation inference") based on attempts to destroy evidence; you might wind up with just extra convictions this way.

For this individual, it's a little late to close the barn door.
