The name "Dragnet" originates from a police term meaning "a system or network for finding or catching someone"()dictionary.com). Originally a radio series, this was the first chance for audiences to get a glimpse of Detective Sergeant Joe Friday on television. The series ran from 1951 to 1959. The television series closely followed the premise and style of its parent radio series, making the necessary adjustments for the television format. The show utilized "documentary style narration from its main character, Jack Webb who reprised his role as Sergeant Joe Friday. Webb was also the creator and director. The show follows Friday, a detective for the Los Angeles Police Department, as he solves crimes throughout the city. The stories in the show originated from the real files from the L.A.P.D. This plus the gritty realism of the police work, full of "dead ends and interruptions of their private lives" made Dragnet one of the "most successful police drama(s) in television history."(TV.com)
In season 3 episode 19 "The Big Trunk", which aired January 7, 1954, Friday and Smith must investigate the murder of a woman in her hotel room. The in which she was killed is clear but the motive is not apparent. They eventually are able to set up recording devices in a room so they can listen in on a conversation between their suspects. They catch the criminal, who claims the death was unintended, and he is committed for murder.

Meanwhile, this little gem (which I did NOT upload) is a fun, fun-filled TV-Drama episode from 1954. Meanwhile, it is completely enjoyable, well-acted, well-produced, well-meaning, well-written, well-uncopyrighted and well-edited. No, it doesn't star any comedians aged 39.

Plus, it is better than the following:
GTV-9 Melbourne
New Coke
Windows Vista
The Bombing of Dresden
Walt Disney Pictures
Prostate Gland Warmer (don't ask)
The Collected Works of Paris Hilton
"Unfinished Music Part 2"

Plus lots of other random things.

The point is, at least it is better than "Dusty's Trail"!!

Quick Update: I admit that I watched this on DVD and not with the file here. Nevertheless, I watched a bit of the uploaded video and picture seemed fine to me.
