Canon Hiruzen likely suspected Danzo for working with Orochimaru and tons of other stuff. Hiruzen never confronted him on it though and look where that got him. Dead. Might as well confront him. Why play dumb when you know the truth? What I would have done is have Jiraiya, Tsunade, and all of the Anbu apprehend Danzo, slap some seals on him, then have his mind cracked open like an egg. The Hokage doesn’t need evidence. He just needs to order his shinobi to do something and they’ll do it. Danzo is a suspect in the attempted assassination of their village’s leader. Have his mind stripped bare.
