You have to accept that these days it is easier to catch and prove the bad guys are guilty.
So there will be less people who are charged with an offence that they did not do.
Once charged and proved guilty, again they should have a better chance on appeal of proving their inoccence.
So the number of inoccent people will be less than before.
I believe we will never have a system that is fool proof, and we will put to death someone who is inoccent.
Now, I can live with that.
Too me, the benefits far outweigh the losses.
Of course, thats fine until, its someone you know!!!!!
