The LMT provides us with video of the exchange that took place last year between a bus driver and a special education student. At first it looks like student is falling asleep and the bus driver appears to be harmlessly teasing the boy. But the UISD employee doesn't relent. He keeps taunting the passenger creating a dangerous driving condition for everybody on board. Check out the first six minutes.
It becomes obvious that the student has had enough as he begins to fight off the driver's bullying. Since then the driver has been terminated by UISD and the mother of the student has filed suit against the district and the driver. In part 2 of the video, you can see the driver pull at the student's hair.
