The evidence is the evidence. A criminal is a criminal. Someone up this chain of thread was making that point.

Evidence is not the evidence. It can be faked.

When you gather evidence illegally, it's easier to fake it.

And illegal is illegal. The investigation agencies have to make their case within the bounds of the law, they are not above it.

Yeah, meanwhile, you're going to have cases where you sent someone to prison(or perhaps killed them) and have absolutely no reason to believe the verdict was undeserved. Everyone thinks that the court cases will go like this.

Judge: Did you obtain this evidence illegally? Prosecution: Yes we did, your honor. Judge: Okay, trial on that starts Monday.

No...you'll have to legally make it so the exclusionary rule is not a defense...i.e, the number of times that this is even brought up will inevitably diminish to 0. Admittedly, it does exist, but the legal system tries it damnest to remove gray areas. At the very least, you will need a legal test to prove that the evidence was not manufactured. You know of any?
