No fingerprints on the murder weapon?
So they didn't have the ability to fingerprint the weapon? I don't recall him taking the blade or wiping it off. Geez, what inept police! Seems to me that Ed's prints would be all over the office yet he got off scott-free! At least until the end, where he got the blame on a murder he didn't commit and couldn't prove innocence because he had killed the REAL killer!
Other than that, it was a well-made movie though a bit contrived.
