Here you see footage recorded on a cell phone by Narces Benoit.
The police are surrounding a car driven by Raymond Herisse. Then they started firing at the 22-year-old.
Herisse was killed, three officers and four bystanders were injured.
Benoit and his girlfriend, Ericka Davis, are accusing authorities of destroying evidence and intimidation.
They say the only reason this video is still around because they were able to hide a memory card before authorities smashed the phone that captured this incident.
They have hired a lawyer, saying they want the right thing to be done.
