Compare that to the crimes that Anwar and Rafizi have been alleged to have done.

Rafizi is facing chargeS under the OSA and criminal defamation.

Anwar, was found guilty of corrupt practices and more recently, sodomy.

Regardless of whether they actually committed the crimes they are alleged to have committed or not, comparing their cases and this case, which is more serious?

Hence, the difference in the raids.
