Get things in perspective
If my house was burgled and I had valuables stolen, sure I'd be a bit dim if I didn't have double locking doors or my wife's jewelry in a safe, but I wouldn't be the criminal.
Sony may be a lot of things and upset quite a few people but ultimately these hackers got into the Sony systems ILLEGALLY. They STOLE information. They commited CRIMINAL acts.
I don't see many people having a go at these hackers, these are the buggers with my private details!!!
