I've looked at many, many criminal court cases with these questions in mind and it really isn't that simple in court. Judges and prosecutors very often and truly don't give a fuck. Or the prosecution will just nolle the case if issues of facts come up. That happens with a lot of technology oriented cases, eg shotspotter and stingrays, where 4a issues are dropped. See [1].

Please realize that defense counsel is fighting an uphill battle while their client is stuck in pretrial limbo. The issue of parallel construction, with some exception, will not really come up. As many lawyers have told me -- what matters to them is getting their client out of jail/pretrial. And because that's the concern over all else, the publicly available information about these abuses simply don't come up in the public eye. So these problems go and go and go.

Really, a lot of what you hope happens in court just... really fucking doesn't. All that'll happen is people will be in jail longer because so many people were arrested under 4a-violating arrests and the defense attorneys get more work load.
