There's an overlap between privacy, civil liberties, and anti-discrimination concerns where laws that can be selectively enforced get disproportionately applied to any and all groups that have 'isms' attacking them.
I confess that while I used to spend quite a deal of time thinking about this class of problem, I haven't done much of it recently, so the following is a mix of potentially outdated thoughts and speculative nonfiction.
If you have the privilege to be outside of any or all of those groups, I feel like it falls on us to speak up to ensure that other people are okay, and Good Samaritan laws can be problematic in this respect, because it's too easy to convince a jury to deny 'those people' standing.
I wondered in another response if some sort of self-reporting system would better serve this space. Possibly 'feature-parity' with other citizen-action laws where community policing and reporting are carried out. The latter closes out a learning opportunity however because you're identifying and reporting a suspicion of an issue and allowing The Authorities to look into it. "We will take it from here." doesn't afford you the opportunity to become part of 'we'.
Perhaps there's precedent with confidential informant laws, and we need to reframe white hat hackers under that umbrella.
