Yes & no. Sadly case precedent in matters like this typically favor law enforcement & prosecutors for multiple reasons. One of them being where they argue if they make the ruling retroactive, then thousands of convicts where they used similar evidence would also be eligible for appeals or dismissal. Another more messed up reason is that if evidence is obtained illegally, if it still "proves" a defendant is guilty, the courts have came up with certain exceptions where it can still be used.

Slight correction:

Soap, ballot, jury, (you are here) ammo.
