You have to go thru a process to prove that it isn't tainted.No. That’s not it.
It’s close. But that’s not what it means, exactly.
To be admissible, all evidence needs to have a proper foundation laid. If some evidence (or piece of evidence) is allegedly tainted, an objection to its admission will lead to some voir dire about the evidence and maybe it’s bona fides including (sometimes) the chain of custody. Then the judge makes the call.
What I’m saying is that opening the box doesn’t necessarily “taint” that evidence — because the party offering the evidence may still be able to establish that it nevertheless is what it purports to be and hasn’t been altered (and also they need to demonstrate that it’s relevant to some material issue in the case)
We're saying the same thing....but just saying it differently.
