A familiar wave of anger erupting on American streets on Wednesday night. Chants of murder and black lives matter. Demonstrators demanding a federal investigation into the shooting of an unarmed black man by police in Southern California.>> Police are terrorists, killing people more than ISIS.>> Reuter's Dan Whitcomb is on the scene.
>> I'm standing in front of Poncho's Tacos here in El Cajon, a San Diego suburb. This has been sort of the epicenter of protests here in this suburb over the shooting of an unarmed black man, Alfred Olango. The past two days have seen a number of street protests, culminating earlier this evening in a tense standoff between the demonstrators and police.
>> Stand up for the bullshit.>> Tensions began on Tuesday, after Olango was seen walking around in traffic. He had a history of drug and weapon convictions, and reports say he was mentally ill. Police say they approached him and opened fire when he pulled something from his pocket.
But no gun was found on his body. Authorities say they have cell phone footage of the shooting from a bystander. But they've only released a still frame showing Olango aiming an unidentified object at two officers. Protesters on Wednesday night demanding that the whole video should be made public.
One person who has seen it is El Cajon Mayor, Bill Wells.>> I saw a man who was distraught, a man who was acting in ways that looked like he was in great pain. And I saw him get gunned down and killed, and it broke my heart.>> According to Wells, the FBI has joined the investigation, along side the San Diego Country District Attorney.
Police say the cell phone video will be released once the probe is complete.
