Remember in every system people push up to and just as far over the line as they can get away with.

'Good faith' is given when chain of custody is broken. 'Good faith' is given way too much. Either the 4th Amendment is serious enough to have power/force over law enforcement/judicial, or it doesn't. And with good faith, it doesn't.

'our side violated the law but because of the divisions of power, our side didn't violate the law and we are going to give good faith to our side that our side was acting in good faith'. It's all window dressing to say 'the fourth amendment is superseded by other factors that a judge get's to decide at their discretion and the fourth amendment is not in fact the law of the land, a judge can overrule it with 'good faith''.
