In case you've been living under a rock for the last while: several American states have banned abortions[0][1] after the Supreme Court overturned Roe vs Wade. The federal government failed to implement any laws to safeguard access to abortions so overturning Roe vs Wade was all that conservatives needed.
Some states have exceptions for rape and incest, some don't. Texas even offers a sizeable bounty for reporting abortions. This has already resulted in medical care being refused to women carrying stillborn children and other pregnancy complications fatal to either the mother or the child out of fear of prosecution.
As for secondary criminal activity: I agree, if the police finds other illegal acts during a legal investigation, they should be allowed to act on that. This is the proof that the whole "if you've got nothing to hide" narrative surrounding state surveillance is dangerous.
