I disagree. DT checks should be used to find mafia, and not to confirm innocents. Trying to confirm innocents is just a waste of time considering the possibility of a godfather/roleblocker. If a DT tries to find a red, but find a town, then you get an innocent to start a circle with. If you hit red, share it with the town.
Are you confirming their innocence or persuading us they don't need to be checked.
