"Dallas today is different than it was yesterday and definitely different than it was a year ago," DPD Chief U. Renee Hall said Wednesday night.
During the trial, DPD Sgt. Breanna Valentine said that DPD Sgt. Mike Mata, the president of the Dallas Police Association and Valentine's superior officer by virtue of service time, told her to turn off the in-car camera system that was filming Guyger as she sat in a police vehicle after shooting and killing Botham Jean.
"What you saw and heard was disheartening, and I can only imagine the public's perception of who we are as a police department," the chief said.
“I welcome it and want a thorough investigation of all parties who were at the scene that night,” Mata told
The Dallas Morning News. "And when this investigation is done, it will show that I violated no policy and I did the standard practice that has been in place for several years.”
The testimony that came out in this trial is not reflective of the men and women in the Dallas Police Department," Hall said.
Internal affairs will also investigate Rivera, who remains employed by the department, Hall said.
"We're not backing away from those things," Hall said. "As a department, we're always assessing ourselves."
"The Dallas Police Department is not what you've heard over the last week and a half," Hall said.
