The Wrong Man (1956)
The next morning when they cone to get him for arraignment, he is wearing his tie.

One piece of evidence the police actually try to use against Manny - the holdup note that he gave to the clerk. If Manny committed the crime, then his prints would be on the note - case closed. If not, he would be exonerated.
But instead of checking the note for fingerprints the police go through the ridiculous fingerprint "analysis", all the while handling the note without gloves.
Simply dusting the note for prints and comparing the results to those taken from Manny would have solved the whole case.
But then again, if they had done so, end of story, end of movie. :)
