A Texas gunman who called himself a “sovereign citizen” not bound by US laws was killed in a shootout with cops while livestreaming on Facebook.

Patrick Hurst, 47, told Harris County deputies who pulled him over for an expired registration and busted tailgate in Houston on Sunday that he would not comply with their orders because he was a member of the extremist movement that doesn't accept the legitimacy of government institutions.

He drove off soon after cops learned he had a possible open out-of-county felony warrant for evading police before he was stopped with spike strips.

Hurst then streamed on Facebook Live as he pulled a handgun and jumped out of his car to confront the pursuing officers — getting killed after firing first at the deputies, Sheriff Ed Gonzalez said.

Does WPD have the stream?
