You and others (top-level comment spawning this subthread) seem to be implying (correctly, I think) that immigrants are afraid to engage with the medical establishment (or police... they're all lumped together under "authorities") because they're worried about getting caught up in the immigration enforcement dragnet. The obvious solution to distrust and lack of engagement between immigrant communities and the authorities — unless you have another non-obvious one — is to stop enforcing immigration laws at all. In other words, the government should never check someone's citizenship/immigration status, except maybe when someone's caught committing a crime (maybe... at least if it's a serious crime... then we'll check immigration status and send them back if they're not a permanent resident). That's what set Al on tilt, because it is essentially an open borders policy.
