VIDEO: Teen Shot by Police in Ferguson Protest Had Gun

The teenager shot in Ferguson, MO on Sunday night by police is seen on video with a gun right before he was wounded, according to officials. Tyrone Harris Jr., a friend of Michael Brown, was shot Sunday night when he opened fire on an unmarked police van at a protest to mark the one-year anniversary of Michael Brown's death.

In a 13-second clip taken from a security camera of an insurance office on West Florissant Avenue, Harris, 18, is seen grabbing a handgun from his waistband and opening fire on plainclothes cops.

Harris has been charged with a bunch of felonies, including five counts of armed criminal action and four counts of assault on law enforcement.

Harris' father disputed the police account of the shooting, but has not yet commented on the video release.

An armed militia-type group called the Oath Keepers has arrived in Ferguson to "patrol" the streets. "The group wore camouflage bulletproof vests and brandished rifles on West Florissant Avenue, the center of protests for the past several days."

The police chief was not happy with their arrival, calling their presence “both unnecessary and inflammatory.”
