Don't know if the script writer did it intentionally but Flint does a really horrible job of detective work for most of this episode.
Sandy Dennis would return in Carrier.
Eleanor: (to Flint about Rhodes) I had to shoot him, you see, because I love him.
Flint: She said she shot you because she loved you.
Rhodes: She what? I never saw that girl in my life!
Parker: The trouble with you, Adam, is you always have an opinion. An opinion is for a jury not a detective second grade.
Arcaro: I get more phone calls than a bookie.
Libby: It's almost classic. Like Hester in The Scarlet Letter.
Flint: Only Hester didn't shoot the Reverend Dimmesdale with a revolver.
In the football sequence, Elvin Rhodes is seen playing defense but by 1962 (the year the episode was filmed) the one platoon system was obsolete in professional football.
Nitpick: Elvin Rhodes wears number 99 on his football jersey. This is a very high number for an NFL RB. Most RB's wear jersey numbers in the 20's, 30's, and 40's.
The QB for Elvin Rhodes' team wears number 60 in the stock footage but wears number 16 in the live footage.
