The Outcome
This is just another example where an American wants to make a fast buck my sueing someone. A survey was conducted asking American's how they would get rich and the majority answered by sueing someone.
The couple concerned can't sue a member of the public that might have actually accessed the pictures and posted on to the net because they have no idea who it is, so in order to become rich, they have to sue MacD.
I dunno about US courts, but if this was in the UK, the defendant simply has to say "the access of the images took place whilst the phone was not in our possession. They left it on a table, that's their carelessness and we are not responsible for what happens to the phone before it was handed into us. The plaintiff should ensure that if they are sending such sensitive images to each other then they should take appropriate precautions to ensure the security of those images, such as putting a pin code lock on the keypad, which the phone almost certainly provides". Case dismissed. Judgement in favour of the plaintiff.
And they'd end up paying the court costs of MacD.
