Possibly Encinia had in mind Chapter 542, Section 501 of the Texas Statutes, which says "a person may not willfully fail or refuse to comply with a lawful order or direction of a police officer." In the video Encinia repeatedly says Bland has refused to comply with his lawful command to exit the vehicle, which is what leads him to threaten her with his stun gun, saying, "Get out of the car! I will light you up. Get out!" Bland says he has no legal right to demand that she leave her car based on a minor traffic infraction. Encinia insists he does have that authority.
Sadly, Encinia seems to be right, thanks to Pennsylvania v. Mimms, a 1977 decision in which the U.S. Supreme Court said a police officer may order a legally detained motorist out of his car at will. The case involved a man named Harry Mimms, who was stopped by Philadelphia police for driving a car with expired tags. After Mimms was ordered out of his car, the officer noticed a suspicious bulge under his jacket that turned out to be a gun. Mimms was charged with illegal possession of a concealed firearm, and he tried to have the gun excluded as evidence by arguing that it was obtained in violation of the Fourth Amendment's ban on "unreasonable searches and seizures." The Pennsylvania Supreme Court agreed, saying the officer needed some specific reason, beyond the traffic violation that resulted in the stop, to force Mimms out of his car. The U.S. Supreme Court disagreed, saying general concerns about officer safety are enough to justify such an order:
