well, that's what i'm wondering. In a hypothetical case where this was different (no admission), how do states handle evidence collection that may be legal in one state but not another? Do they treat it as "this shit landed in our lap, so not our problem" as they would hacker dumps?
Well the abortion was legal in Indiana when the evidence was collected. I feel like it would be hard for defense to argue the evidence was collected illegally just because now abortions are illegal in Ohio. The way the evidence was collected was legal in the location it was collected. The defendants's rights were not violated by the collection since the victim consented via a legal guardian to the collection.
The claim would hold merit only if the evidence was collected illegally or violated defendent's constitutional rights. the defendent has no right to privacy to the girl he raped and the SC just said there is no right to privacy. So Ohio can outlaw abortion but INdiana legally collected the evidence. There was no police misconduct, illegal collection or violation of any law to get it.
