Consider me cynical, but when the conservatives on the Supreme Court seem to be the strongest advocates for victims rights, I can't take their opinions at face value.
Since this ruling only applies to searches for evidence, the real impact on domestic abuse is unknown. Even though domestic abuse issues have been linked to this case, the real fight might be about attempts to loosen the restrictions on what is considered an unreasonable search.
This might be an attempt to erode civil rights cloaked as an attempt to protect victims rights. For once, I hope I'm wrong.
