That isn't specific information - that is more speculation.
I expect people who make positive claims (the database contains innocuous images) to be able to back up those claims. Saying that there are innocuous images in the database is completely different from saying there may be innocuous images in the database.
It would be like if I claimed that there is a burglar in your house - and how do I know? Well all a burglar would have to do is break your window and crawl in.
