1. The young man OWNED the motorbike he was accused of stealing,
2. The keys were in his pocket.
3. A simple vehicle check would have confirmed ownership
4. The man's body was in shock from being punched as can clearly be seen in the footage.
5. No ambulance arrived on the scene, though one was called but later CANCELLED.
6. No medic was at the scene to check the man's state of health and his injuries.
7. Less than 24 hrs after the incident, a conclusion of no action required was made by the officer's superiors.
8. Rachelle Henry was the Lady who captured the entire incident on film outside her home ,had she not done so nobody would know how dangerous this officer is. 
9. A petition is online started by Rachelle  

Conclusion

This action looks highly like an officer of the law racially profiling, culminating in a racially motivated attack, REASON: his white friend who was present during the assault, was not touched.
