The worst part is companies like yahoo, google, cell providers like ATT etc all hand over data to law enforcement WITHOUT warrants! http://www.forbes.com/sites/andygree...he-government/
I've seen on sites yahoo's LE req form, they've even streamlined the process. They will all hand your data over in a heartbeat. That is, if they're not allowing LE to search their database whenever or backdoors to look at anyone's account whenever they want. Nothing surprises me anymore. I know its all possible, even easy (I've a bach degree in computer science)
