A court in the US state of Louisiana has released a video showing law enforcement officers fatally shooting a 6-year-old autistic boy last November. �

The tape shows two deputy city marshals opening fire on a car, killing the boy and critically wounding his father in the city of Marksville.

Jeremy�Mardis, who had autism,�died at the scene from multiple gunshot wounds. His father, Chris Few, survived.

Prosecutors showed the tape in court to support their claim that one of the deputies had a pattern of using excessive force.

Police say the officer�s chased the boy�s father�Christopher Few after he drove off from an argument with his girlfriend.

Defense attorneys argued the deputies acted in self-defense and claim the boy's father rammed into a deputy's vehicle before they fired.

However, the judge said the footage doesn't show the boy�s father using his car as a deadly weapon at the time of the shooting.

The release of the video came days after several African American men were killed by police in the states of California, Oklahoma and North Carolina.

A state of emergency and curfew were imposed for several days by authorities in North Carolina to quell unrest in Charlotte.

On Wednesday, protests have erupted in El Cajon, California, to condemn the police shooting of 38-year-old Alfred Olango who was reportedly mentally ill.

The rally continued into the night with hundreds of people marching from the shooting scene to El Cajon City Hall and back again, shouting Olango's name, insulting police and disrupting traffic.
