Vader also “somehow forgets” to read the mind of Captain Antilles, the captured Rebel Troopers and Princess Leia to find out where the Death Star plans are and where the hidden Rebel base is. There you go, a similar contrivance just as you asked for. Now please stop being such a pedantic killjoy!
Does Vader have the ability in OT to read minds? I never thought that. As Vader used torture to get information i.e. with Leia and Han.
