That means that the FBI would have to help every filmmaker everywhere.

Nope, it just means they'd need criteria other than what makes them look good. Which in fact I'm pretty sure they already must have, besides the PR angle.

The solution to bad people doing bad things can't always be to hack the legs off of everyone at the kneecaps and put everyone in a "safe" wheelchair.

This is an extremely broad argument to a particular situation, and those are rarely fruitful. But in any case: Bad people are rarely the real problem, they are relatively few. The real problem is culture and institutions that lead regular people to do bad things. Facilis decensus Averno. And if in a private context I believe the imposition of such rules should be avoided, I don't think the same applies to a public institution.

A better solution is that if you see a government agency misrepresenting themselves in media... point it out. Freedom of speech and freedom of press are there for a reason.

Point out what, that film makers are portraying a certain institution better than they would've had there been no help? How would I know? It's not like I'm claiming they would require outright lying or anything; it's just that it can introduce subtle but dangerous bias in the whole process.
