About 5:40 on Saturday afternoon; the Iraqi security forces blocked the main street of Jadiriyah neighborhood was blocked because one of the Iraqi officials was passing through. The drivers were waiting for the convoy to pass. While they were waiting, a US military convoy came from behind. The driver of the first humvee saw the real long of the stopped cars and I'm sure he knows for sure they stopped because the street was blocked. Yet; he didn't stop. He used the horn and he kept hitting a sedan Mercedes in front of his humvee. The driver of the Mercedes took his hand out of the car and waved to the humvee driver as if he was telling him to stop hitting the car because the man doesn't have any choices but the American soldier kept hitting the car. He kept doing that for more than three minutes. I was on the other side of the street trying to get a taxi to go home. I left the street while the American soldier was enjoying hitting and bothering the poor Iraqi man who could do nothing because he knows for sure that he might be killed if he thought about going out of his car and tried to ask the soldier to stop.
