Why fear to give a copy of police report?

Wondering, why police are so fear to give a copy of police report [lodge by Saiful] to the defendant, in this case Anwar Ibrahim. If the report was done without any conspiracy or ill intention, then police don't need to worry to deliver a copy. In 2nd sodomy allegations, it's look and sound viet where the defendant are begging for the copy but the police are running away with various reason. Well, this new allegations will really backfire not only NTR but umno in specific and BN in general.
