Regarding my last post, if something is lacking, such as admissible evidence, does that mean that there might be inadmissible evidence?

Just wondering . . .what if there is evidence that because of some legal issue is not admissible in a court?

We’ve all heard of it. It could be either illegally obtained or collected or might have been mishandled.

The question- is there some inadmissible evidence out there that we should know about?

Just wondering . . .
