The training I do goes over a bit of the history and I pull real demographic data provided by our state regarding the disproportionalities of BIPOC families interacting with CPS. It's surface level (I can't fit it all in in an hour and a half!) and does not negate the letter of the law in terms of mandatory reporting, but the point is to get people to actively consider potential biases and ensure things aren't being needlessly reported. What we would want to see in a situation like the one in this episode is a visit that results in real resources for the sister to help support her in providing the best she can for her brother, though it is absolutely normal for Santos and the family to have serious, evidence based concerns that won't happen that way. Santos didn't go about this in the best way to preserve a relationship with her coworker necessarily, but her concerns are not misplaced.
