Intentional

Today he only wanted to accompany his son but he never expected that something like this would happen while he was waiting for him and because of this he even needed to ask his wife to pick their son from the school in his stead.

The police and the ambulance soon came that's why they managed to bring the man to the hospital immediately.

Officer Kang also told everything he saw to his fellow officers before leaving everything to them, since he is on a leave it was fine to do so and it's not like he was slacking off, he followed the ambulance to the hospital where the man was brought to.

He witnessed the scene exactly and he felt that what happened was intentional but he didn't dare say this to others because a formal investigation is still needed before coming into a conclusion. Furthermore, he knows that he cannot carelessly speak matters like this.
