On Hannity last night, we heard the police chief's account of what happened before a policeman fatally shot an unarmed black teenager in Ferguson, Missouri. Thomas Jackson said that there was a struggle between 18-year-old Michael Brown and the officer, leaving the officer with injuries to his face.

He said at one point, the officer's gun went off inside his vehicle in the altercation with Brown.

Witnesses, however, have given starkly different accounts and Fox News legal analyst Peter Johnson Jr. broke them down this morning.

Here's the version of events given by Dorian Johnson, a friend of Brown.

- The officer told the two men to get on the sidewalk.

- Officer tried to open his car door, but could not because the two men were so close to his vehicle.

- Officer grabbed Brown by the neck and tried to pull him into the car.

- Officer pulled out his weapon and fired, hitting Brown.

- The men ran and the officer pursued, shooting again.

- Brown got down on the ground, put his hands in the air and yelled, "I don't have a gun. Stop shooting!"

- Officer stood over Brown and fired several more shots.
