>There's a chance that doing so might increase the likelihood of harassment again in future
I'm probably already at max likelihood already. I am detained 4+ hours everytime I enter the country. In 2015 I fought alongside the Kurdish militia YPG in northern Syria against ISIS, and ever since the CBP has targeted me. There is a flag on my passport that basically says 'harass him' as best as I can tell.
>if you can, find the relevant anti-corruption agency and report the events to them.
Still in the process of filing the complaints against the relevant medical professionals who violated patient consent. I am currently working in order of operations from where I expect justice to be most likely (complicit medical workers) to where I expect justice to be impossible (CBP officers).
