One of the hardest things I had to deal with was investigating valid complaints from the public about our drivers. The problem was so bad that in about 2012 I put on our trucks one of the first 360-degree camera systems in the country that recorded in HD and stored the video for a week.

The very first truck that had it on the first week had a complaint form a woman that claimed that garbage fell off the truck and damaged the grill on her BMW. She went to the highway patrol and they contacted us.  I spent over an hour watching video from the truck and her car was never near our truck nor did any garbage fall out.   

What I don't understand is that these camera systems are available and they are cheap and easy to install.  in 2012, I had to source that parts from China and other locations just to get the parts.  

I suspect that there is video of your complaint and they just don't want to show it to you or even look at it themselves.

I suspect they are afraid of the union. And the director is a political hack.
