1. tear gasing the protesters, they ask the protesters to protest at night

2. Excessive force is when an officer or person of authority abuses their power and uses too much force/violence to adress situations. I think excessive force was definitely used in the shooting, for the shots were spread out and the victim had his hands up.

3. I would let the people know that the town and federal government are going to investigate the case further, and keep the police officer under supervision or house arrest until they solve the case whether or not he shot the victim for no reason.
