"the Commission does not disclose the existence or non-existence of an investigation" seems to make it clear that law enforcement activities may not exist either. In order to comply with that, they would not be able to answer something like 'we do not have any records because there is no investigation', so you necessarily get a vague letter like this that seems like it may be suggesting there is an investigation.
