When Friday examines the gun that Carl used to commit suicide he says " a .38 Colt." But the revolver he picks up and unloads is very clearly identifiable as a .38 Smith and Wesson. It's odd that Friday handled the gun which would corrupt any other fingerprints that might be on it.
In the introduction it's said that Los Angeles is the largest city in the United States. It was the largest city in California Not in the United States.
After leaving the home of the suicide, Friday says that he and Gannon went back to the office at 1:37 AM. The camera shows their car pulling into the station in the dark, but there were no headlights or taillights illuminated on the car.
Mrs. Gaynor explained the entire story about how she killed her son-in-law. Her son-in-law had come to the house uninvited and drunk and had pulled out a gun and threatened Mrs. Gaynor. He refused to leave even though he had been ordered to do so several times by Mrs. Gaynor. He displayed violence with the firearm by grabbing her bible from her hands and firing a shot into it and throwing it into the fire place. Considering the age of Mrs. Gaynor and all of the other elements this would have easily lead up to a case of self defense as Mrs. Gaynor had shot her son-in-law in fear for her own life. Instead they went with an insanity plea claiming that Mrs. Gaynor was insane at the time of the incident. A weak defense due to the fact that people are rarely, if ever, insane only for a brief few moments.
The window glass shatters after Friday barely taps on it with his flashlight; so it was either pre-broken, or not really glass.
The mother-in-law is nowhere in sight when the gunshot is heard and the man allegedly killed himself. They have to go fetch her, sleeping in her room. Yet, when questioned, she admits having been with her son-in-law up until moments from his death. Yet, the cops (Gannon, Friday) don't think that it's odd, that a gunshot rang out while they were desperately trying to break into the living room. Yet, she admits to have been there, with him, and never once bothered herself to open the door for the cops, nor to talk to them. She simply, casually, went back to bed knowing there was a death in her house. She isn't so much as questioned about why.
They make no mention of doing a gunshot residue (GSR) test on either the deceased or the mother-in-law to verify parts of the story. GSR tests had been around for decades at the time this episode was filmed.
The actress playing the wife, in the pink bathrobe, asks "is he still alive?" to Friday, as matter-of-factly as if she were asking "is he still sleeping?" and she isn't questioned about that.
