The shooting of 38-year-old Alfred Olango, a Ugandan refugee, led to violent protests in El Cajon.

Police said they shot the man when he pulled an object that turned out to be an e-cigarette from his pocket and pointed it at a police officer.

One of the videos of the incident was recorded by a surveillance camera mounted at the window of a drive-thru restaurant, while another came from the mobile phone of a bystander.

In the second video, which lasts less than 20 seconds, a woman can be heard shouting: “Officer don’t shoot him!” before at least four shots ring out and she screams.

El Cajon police chief Jeff Davis said Alfred Olango died after one officer fired an electronic stun gun and another officer simultaneously fired his firearm several times.
