According to gossip site Page Six, Snider's crew is making a "documentary rock video" for his song So What at Standing Rock, North Dakota, which his son Cody Blue Snider is directing.

The 61-year-old musician and his crew were reportedly caught up in the clashes between protesters and police recently, as the Standing Rock Sioux tribe protest against plans to construct a 1,170-mile long pipeline which would run across four states.

Snider's director of photography Alexander Chinnici, was reportedly shot with a rubber bullet, as he captured the event.

Following the incident, Cody took to Twitter, writing, "I'm filming the DAPL resistance & was tear gassed, while our camera man was shot with a rubber bullet. Freedom of press is a farce. #NoDAPL."

The filmmakers reportedly continued to shoot even after being tear-gassed amid the violent clashes which saw unarmed protesters have "flash-bang" grenades thrown at them and get hosed down by water cannons.

"To see US government state and local authorities, along with hired private security, use this type of extreme violent force against unarmed American citizens in peaceful prayer is the saddest, most disturbing thing I have ever experienced," Snider said, according to the news outlet. "I’m glad we were there to capture the truth for all to see."

While the We're Not Gonna Take It hitmaker and his film crew reportedly escaped unscathed, hundreds of other people were involved, with one female protestor sustaining a serious arm injury from an exploding flash-bang grenade.

And the frontman tweeted earlier on Monday (28Nov16), "This is about all of our water and all of our environment. It's time to make a stand!"

Snider’s documentary rock video featuring the Standing Rock footage will be released later this year (16).
