It does if they're found innocent after conviction, as has happened at least 347 times so far[1].
It should also be noteworthy to the true law and order types that false convictions mean the real perpetrator is still going unpunished. If you kill everyone who does something you dislike, the pressure applied by those bleeding hearts at the Innocence Project will go away, which means now not only have you killed someone innocent, but you've pointed blame away from the guilty and basically assured they'll get away with it. I must confess my failure to understand how this outcome is supportive of law and order.
And with regards to the comment about surveillance and DNA testing, you might benefit from a bit of reading about the history of forensics. It is a history of foolproof methods being rather less than foolproof. Of if you really can't dismiss the idea that we've achieved the pinnacle of physical evidence analysis, at least do some reading on what is actually involved. Remember that with, e.g., DNA testing for legal purposes, you're not looking at just the test: you're looking at the whole "stack", from our understanding of biology to the lab performance to the chain of custody to jurors' understanding of science. Not going to point to anything specific; there are a ton of explainers out there about this waiting for the interested.
I'll end with a simple question: do you believe that Blackstone's famous ratio is false?
"It is better that ten guilty persons escape than that one innocent suffer[.]"
