"breaks into"? Errm, they have the keys to the door. They own the house. No one broke in. Hotmail users give MS permission to look in their email when they agree to the T&Cs. So using an account hosted by them to conspire against them was pretty boneheaded to say the least.
Yeah this was a pretty sad attempt to hide. So much so that I almost wonder if it was actually intentional theft.
"Courts do not issue orders authorizing someone to search themselves, since obviously no such order is needed. So even when we believe we have probable cause, it’s not feasible to ask a court to order us to search ourselves. However, even we should not conduct a search of our own e-mail and other customer services unless the circumstances would justify a court order, if one were available."
