It's an unfortunate fact that eyewitness testimony is inherently unreliable. Sometimes witnesses to a crime can't even agree on whether the attacker was black or white, had short hair or long, did or didn't have a beard, jumped into a car or ran away, etc. And it's been shown repeatedly in studies that people will often change their memories according to coincide with what others are saying. Memory is definitely flawed and highly volatile.

Which is not addressing the whole JFK thing, a matter about which I have no opinion.

But I'm sure many tens of thousands or more people have gone to jail or had their lives and careers ruined by mistaken eyewitness testimony given by perfectly good people with the very best of intentions. I don't believe in coddling crooks one bit, but it's no loss that eyewitness testimony is sometimes not just taken for granted as being perfect proof.
