follow-up report News 8 asked if the Dallas County Sheriff's Department was concerned about Westbrook's actions that day.  "We are looking into the conduct," said department spokeswoman Carmen  Castro. "There has been no official investigation brought forward, but  we are looking to determine if his conduct was appropriate for the  situation at hand."  "Of course it's over a hundred bikers.  Who are you going to pick?"  Castro asked. "The ones that are going to help you a little bit more or  had the video camera that would've assisted more."  When asked whether a warrant is required for the kind of traffic stop made by Deputy Westbrook, Castro offered no response.  The department released its own dashcam video Wednesday as proof that  a group of bikers posed a public safety threat. However, the video did  not come from the deputy who made the arrest, and at this point, it does  not prove that the biker who was arrested was in any way involved with  that group. more info here... http://www.wfaa.com/news/crime/Dallas-Sheriffs-Office-looking-into-deputys--159806175.html
