If this were absolutely the only use of such data slurping, then yes. The problem is, with such secrecy and an unwillingness to allow independent oversight, its hard to believe that. The problem is all the other uses of such information. And of course we have no idea what else the information is being used for. There is also the effects on people who don't know. For example, imagine the politician who wants to reign in a security service for over reach, but suspects that the security service in question might have some embarrassing data on him/her. Would such a politician take the risk? Or what if a candidate wanted to fight an election based on reigning in a security service, and the sitting politician was "helped by the security service at risk. And so on... Such information has great power to destroy what democracy we have.
