Rav Dovid Kav ztz"l was a senior Ra"m in Yeshivat Kerem bi-yavneh who was niftar a few days ago. Years ago, a former student of his in Kerem Bi-yavne was accused of murdering Yitzchak Rabin. Rav Kav was arrested by the Shin Bet on suspicion of teaching his student that Rabin had a din rodef and he was thus an accomplice to the murder. He said to his interrogators - "Do you want to know what a rodef is?" They said yes.
He then gave a SEVEN HOUR SHIUR on the sugya of rodef. When he finished, the interrogator, who was writing down every word, said "according to what you said, the murder had nothing to do with the din of rodef?"
Rav Dovid looked at the interrogator, straightened his beard, sat straight in his chair and said "יפה הבנת את השיעור." ["Nice. You understood the shiur."]
