In flagrante delicto/ in the very act/ at the time of doing
In the course of doing the deed. At the time of the action.
(Since intentional is called sinner, and unintentional is called sinner, what is intentional - that he had knowledge, likewise unintentional - that he had knowledge. Rabbi Akiva said to him: Let me add to your words, if what is intentional - that the knowledge was in the very act, likewise unintentional - that he had knowledge in the very act - he said to him: Behold, and all the more so that you added.)
