A vicious law-and-order zealot becomes inflamed by various thugs getting off the hook in court on technicalities. So, using an alias, the man sends a letter to McGarrett promising to blow away the next criminal who takes a walk -- naming a specific hood in particular. The criminal walks and is drilled right in front of the courthouse. As a public debate rages on vigilante "justice," the killer sends McGarrett another note, expanding his hate list to the judges who order charges quashed on technicalities. A judge (Frank Cady of Hooterville fame in a very rare serious role) does just that and is promptly kidnapped from the courthouse by the zealot. McGarrett must pretend to appease the zealot while tracking him down. Written by Peter Harris

A lot of familiar faces and a pretty good plot...
24 April 2011 | by (Bradenton, Florida) – See all my reviews

For folks like me that saw a lot of television in the 1960s and 70s, this is a most enjoyable episode because there some familiar faces among the guests on this episode of "Hawaii Five-O". Anthony Zerbe, who played LOTS of supporting roles on TV (mostly crooks) is the baddie in this one, but Frank Cady (Sam Drucker from "Green Acres" and "Petticoat Junction") and Casey Kasem (the famous DJ) are also on the show. This, combined with a fine plot, make this one well worth seeing.

The show begins with a defendant being acquitted in a criminal trial because the State repeatedly could begin their case because of a critical no-show witness. While this acquittal is clearly the right legal decision according to the Constitution, an onlooker in the court is not pleased and decides to take the law in his own hands. As the now free defendant leaves the courthouse, a shot rings out--and the man is dead.

Soon McGarrett receives a special delivery letter claiming credit for the slaying. According to 'Mother's Helper', he was sick of seeing crooks getting off and has decided to help McGarrett by killing this bad man! So, Steve has a fan who now wants to help him by killing criminals that just need killing! A bit later, a convicted rapist is being paroled from prison. But Mother's Helper apparently is outraged and kills this guy as well. Like in the other case, he sends McGarrett a letter admitting he did it and talking as if Steve enjoys his 'help'! Now McGarrett needs to figure out how to flush out this murderer. But how? And, if this doesn't work, who is next on this psycho's hit list? Overall, a pretty good episode. Zerbe played a fascinating man--ill-educated but very brilliant in his planning and executions. Well wroth seeing and quite original.
