The Frankfurt raid is one of my “Wait and See” items. More and more people are bringing it up. Since both agencies are supposed to operate below the radar on something like this I am not certain how much information will or can be released.
IF they have the Frankfurt servers and if they are what is believed that they are, they could have a record of anyone who logged on and what they did. Even if not used as evidence in court that provides great leverage to encourage cooperation or so it seems to me.
