Dalel- I wish I could help you more than I probably can right now. I’m in a space of laying low. Going through chemical detox from psychiatric drugs is a very difficult process- and many times a lot of trauma reactions that were smothered by drugs resurface – also traumatic memories and triggers resurface. For me a lot of things from years past resurfaced out of context years later, and it was very chaotic. In some places cops are getting trauma trained- but racism also can also impact policing too. I would suggest helping your brother nutritionally, and also help him identify his triggers. Some of us have trauma from bad therapy, but finding a compassionate therapist can be helpful- Maybe also when he is in a better place and feels safe he can write apologies. It terms of legal aid- perhaps a disability rights focused group could help.
