Seriously. Anyone who has ever done FOIA requests knows how laughably incorrect that is. If it's not an exemption and it's not classified, you can't just deny it.
Furthermore, if it is denied, you can appeal that decision. It's not going to go back to the same person either, it'll go a lot higher on the foodchain. Do you think a commander/director is going to put up with a FOIA officer who is constantly creating work for them by improperly denying requests? Here's what a response to a FOIA appeal looks like[1]. It's comprehensive and needs to give its reasoning.
