Help! Police!

One day I went to the corner store. M. the counterman told me that a boy, a teenager had come to the store and said that he hated M. He told M. that he hated all Arab people. He told M. he was going to kill him, showed a gun and ran away.

M. said that he called the police. After about fifteen minutes an officer arrived. The officer asked him where the boy was. M. said "He ran away. He went that way."

The officer asked why he didn't call when the boy was still there. He told him that if he saw him again to call back. The officer walked out too.
