Traffic stop on Sandra Bland, first dash cam video evidence was tampered with to lessen the public response, right until we noticed that the cops screwed with the video... the same cars go by several times.

the longer version

The portion of the video that has raised questions comes after Bland is in the police vehicle.

In one instance, the tow truck driver who has arrived at the scene to take Bland's car is seen coming out of his vehicle four times in less than two minutes. Texas trooper Brian Encinia can be heard on the audio during that portion of the footage, describing the incident on the phone.

In the July 10 encounter, Encinia asks Bland to put out her cigarette. Bland refuses and the trooper demands that she get out of the car, opening the door with his taser drawn.

the director of the Texas Department of Public Safety said Encinia was in the wrong, according to KHOU..

"A DPS state trooper has an obligation to exhibit professionalism and be courteous throughout the entire contact and that wasn't the case here," Steven McCraw said.

Encinia has been put on desk duty for violating departmental procedures.

DPS Director Steven McCraw. “It is important that her family has confidence in the efficacy of this investigation, which is why the Waller County Sheriff’s Office and District Attorney originally requested investigative assistance from the Texas Rangers; and it’s also why DPS requested the FBI assist in this investigation.”

“This team of investigators is committed to conducting a throrough and impartial investigation. When the Texas Rangers and FBI investigation is complete, it will be turned over for review by the District Attorney, who has indicated it will also be brought before a grand jury,” said Director McCraw.

the answer, is Texas. Remember Victoria Texas police tazing the old man, who was completely legal, but the young cop lost his head, and was in the wrong, for pulling over a car with a legal temp license plate? http://justacarguy.blogspot.com/2014/12/roid-rage-cop-has-been-hitting-donuts.html
