The Krome thing is all rumor
I don’t have evidence against
If the truth is hard to determine, I think that in itself is very worrying. When you have vulnerable people imprisoned and credible fears that they are being mistreated, any response from those in power other than transparency is a bad sign. Giving them the benefit of the doubt as long as they can prevent definitive evidence from coming out is bad epistemics and IMO even worse politics (not in a party-political sense; just in a ‘how to disincentivise human rights abuses’ sense).
It is when our uncertainty is due to a lack of information, and those in power control the flow of information! If the accusations are false, the federal government has the power to convincingly prove them false; if the accusations are true, it has the power to suppress any definitive evidence. So the fact that we haven’t seen definitive evidence in favour of the allegations is only very weak evidence against their veracity, whereas the fact that we haven’t seen definitive evidence against the allegations is significant evidence in favour of their veracity.
