If I was the original poster I think I would look into the camera option which Daniel4 suggested. Provides a means to have material for lobbying and material for evidence, and likely as a
deterrent. I was once riding with my headlight on my helmet during the day, headlight was off, and a construction crew asked if it was a camera. They were up on a roof, long ways from me. I say that to note that guys will pick up on a camera head real quick.
I personally don't use a camera, but it's because folks here are pretty good around bikes.
