I'm a bit taken aback by your statement that there's no licensed oversight. Every institution I worked in at least needed a clinically licensed individual making decisions and intervening as needed. It's scary enough when you have one overworked clinician in charge. I shudder to think of having no one with any real education or expertise running the show...

I would second the idea of finding a way to get a review of the case... it sounds like a really emotionally difficult environment to work in. I hope you can find the support you are looking for. Sometimes trying to change a broken system, or at least bring light to how broken it is can be the hardest thing in the world... I also hope you have access to good supervision. I don't think there's anything wrong bringing your concerns about this incident to your clinical supervision. You may still not get the support you are looking for, but at least it's another option. Also, do you have access to group supervision? It might be helpful to bring up there as well. I've found that my peers had more open ideas and offered better support at times than my clinical supervisors. They were not yet jaded and hardened by the system... Just a thought.
