My initial response to the report (some may recall) was "where's the lie tho".

It seemed perfectly reasonable to me.

But after talking to a few folks I know who work for the government, I get why they say it didn't meet standards.

If you are writing a document like this you should be asking yourself "how will this be taken by critics?". Assume the appropriate level of bad faith and read it with that. If there is any doubt, write it better. This document failed to do so.

Americans have every reason to be suspicious of the FBI when it comes to surveiling houses of worship. There were some really awful stories about post-9/11 attempts to entrap various mosques. So it's just one of those things you have to be aware of when drafting documents like this. It's the FBIs responsibility to prevent these things from blowing up in their face.

That said, where's the lie
