Dumbledore was essentially like the judge (or like witness giving testimony). It's the prosecutor type person you want to yell at, and that was Crouch sr. Sirius in GoF:

Crouch’s principles might’ve been good in the beginning — I wouldn’t know. He rose quickly through the Ministry, and he started ordering very harsh measures against Voldemort’s supporters. The Aurors were given new powers — powers to kill rather than capture, for instance. And I wasn’t the only one who was handed straight to the dementors without trial. Crouch fought violence with violence, and authorized the use of the Unforgivable Curses against suspects.
