Yes, it is helpful. It shows exactly why Obbergruppenfuhrer Mewler should be sacked.
"It’s very unusual for the Department of Justice to permit prosecutors to raid an attorney’s office and that’s because you want to be careful not to get privileged material," said Litman, who teaches at the UCLA School of Law and continues to practice at the law firm Constantine Cannon.
In order to get the OK to raid Cohen's office, prosecutors would have had to get approval from high up — in this case from Deputy Attorney General Rod Rosenstein — and demonstrate to a federal magistrate both probable cause and the need for a warrant instead of a subpoena (such as a concern that Cohen might destroy evidence), Litman explained.
In addition, the probable cause would have to relate to a crime centered on Cohen. "You can’t use it as end run around to get to the client," Litman explained.
There will also be a "taint team" to examine everything before it is handed over to prosecutors to make sure that those conducting the case never see any material that might be "tainted" by attorney-client privilege."
The fact that Rosenstein approved it only shows why he is unfit to hold the office he occupies. Using it as an end run around to get the client is exactly what Mewler is doing. That's perfectly obvious. How could those conducting the case never see the material? They've already seen it.
