Victoria, TX - A student resource officer tased a 16-year-old Victoria East High School student who was standing still against a wall in November.The video, posted Sunday by an anonymous source, shows a Nov. 3 incident in which school officials cordoned off the student in a hallway. At the time, a Victoria Independent School District spokeswoman said in a statement the student was tased after he became "highly agitated" and was "punching and kicking" the walls.The video, which has no sound, shows the minutes leading up to the tasing and the tasing itself. The Victoria County Sheriff's Office, which oversees student resource officers, confirmed the video came from a hallway security camera.Sheriff T. Michael O'Connor said before the student was tased the incident had been greatly de-escalated. The events leading up to the tasing that aren't shown need to be considered, he said."Just seeing a clip isn't going to give you a full picture," he said. "You need to know the totality of the whole case."The sheriff's office did not know who posted the video online or how, O'Connor said. The case is still under investigation, he said.The video appears to be edited. The time stamp in the upper right-hand corner jumps ahead seven times and back once, and it also displays different parts of the school. The portion showing the tasing, however, is uninterrupted.The six-minute video condenses about 20 minutes in the hallway, according to the time stamp.Early in the video, the student punches with one hand a white box housing a fire extinguisher as he walks down the hallway, but the officers accompanying him make no attempt to restrain him.A couple minutes later, the video shows the student standing against a wall. The student stands still for about 13 minutes before he's tased, according to the time stamp.More info available https://www.victoriaadvocate.com/news/2015/dec/22/video-show
