First off thanks for all the responses. Whether critical or not, everyone has wished to be supportive.

When you are faced with such a situation it is self-preservation that takes a hold.

I have PTSD from such abuse I faced myself both in and out of the military. I have on more than one occasion dealt with threats and physical blow-back for confronting and ratting on such predators. My thought at the time was that if I did call for someone to take action that this guy was going to be left alone while packing up his camp. I was terrified of what might ensue. Terrified. Given such panic my defense mechanism is to freeze, not take flight (which could not be done) and not fight.

I mean no offense to the good military people out there but my experience was not positive. There were the predators. Those that were not were predators by proxy - they just stood by. I learned there were ramifications for rocking the boat. This man fit the type and triggered fear as a result.

Yes, I should have done something and I am deeply upset with myself. There is no excuse I know. We all react differently in the face of such fear. My reaction is to cower. I am sorry to her and all those I have disappointed.
