About two weeks ago, two Israeli policemen were shot by Palestinian terrorists. The terrorists pretended to have a flat tyre when the police car stopped in order to help them. As soon as the two cops stopped they were shot in the heads. This happened near the Jordan border.

A few days later, the Toldot Avraham Yitzchak Rebbe, Rabbi Shmuel Yaakov Kahn, received a phone call from the police. Some months ago, the Rebbe had visited Meron together with some of his Chassidim. They were traveling by car when suddenly a police car stopped them in the area where later on, the two cops were shot.
The Chassidim then told the police that they had a famous Rebbe in the car but those cops then insisted on giving the Rebbe a ticket.
I didn't really get the reason. Maybe they drove too fast.

However, when the police called up the Rebbe after the murderous attack, they apologized for giving him a ticket some months earlier. And if he had been so mad at them that he may have cursed the police. Was it a G - dly decree for the two murdered cops ?
The two cops being killed had nothing to do with the ticket but the police were apologizing in general.

The Toldot Avraham Yitzchak Rebbe, however, was shocked. He had the ticket accepted and never ever cursed anyone.
