We've had some discussions here about the possibility of allowing
things into evidence that were obtained by an illegal search and then
prosecuting the LEO who obtained evidence illegally. Although this is
in some ways a side argument to the main issue of the rights of the
person from whom the evidence was illegally obtained, I've always said
that it's unlikely that a jury would convict a police officer
especially if the person whose rights were violated wasn't an
upstanding citizen. At least that's what I think I said.
This article is somewhat on point about that issue. Although it's more
about a LEO who provides evidence instead of taking it. Not enjoyable
reading.
