A blanket exception is if the client asked for attorney help in the commission of a crime. Or if the client asked the attorney to do something unlawful. Those are the main ones. There are others. Is it possible Trump may have asked Cohen to “fix” something and in the process violated one of both of the above?
Ah, yes. The “possible cause” standard.
Can you cite any case law supporting this standard?
Stipulate, for the sake of this discussion, that the raid was legitimate. The fact that it was performed in a manner to completely consume all data from the attorney says that the rules on the DOJ side were likely broken (re: Special master and care for privilege). The data was held by the FBI, supposedly only to be reviewed by “special teams”, but it seems like there were immediate leaks of privileged information casting aspersions on not Cohen or Trump, but rather on some other Republican official.
The DOJ and FBI are out of line, IMHO.
