Best thriller TV stupidity of all time
Stupidity: Farnsworth tells Charnquist they've been compromised by a girl listening in on their phone calls and that Charnquist needs to take care of it. He is able to identify the girl, elude FBI, tries to burn his apartment down, is able to gains access to Maggie's apartment and knock out Aram in order to kidnap Maggie. He's a killer who works for someone who has arranged dozen of murders, and knows "take care of her" means kill her. There is absolutely no reason for Charnquist not to have just killed Maggie, Aram, and Fiona. He had opportunity and he ends up killing 3 cops in order to kidnap her and kidnapping Maggie would not have solved anything.
Stupidity: After talking to the bartender Calleigh goes back the lab and talks to Cain, he wonders if they got a false positive from the vic's blood alcohol. Calleigh then gives a detailed description of how that could happen. Cain already knows how (obviously this was done for the audience, to explain it, but in the context of the show it makes no sense).
Stupidity: West and Gordon are in the coal cart and rock it until it tips over so they can escape. Neither West nor Gordon had their feet tied up, only their wrists, meaning both could have merely stood up in the cart and jumped out of it, rather than rocking it side to side.
Stupidity: In the final scene: Columbo lays a trap for the murderer (George Hamilton). The 'eyewitness' when Hamilton fled the murder scene was a blind man. Hamilton is aware of this. Columbo's gambit depends on Hamilton's assumption that Columbo has coached the witness to act as though he was sighted so as to convince Hamilton that there is evidence against him. In fact, Columbo has the witness' brother, who is sighted, pretend to be the eyewitness and identify Hamilton as the man he saw driving away. When Hamilton falls for Columbo's trap and, believing he is in the presence of the blind man, tries and fails to 'prove' the man can't see. By doing so he reveals his knowledge that the witness was blind, incriminating himself. The problem is, that only a minute or so previously, Columbo had placed Hamilton under arrest, and failed to read him his Miranda Rights. Considering that Hamilton's slip up is the ONLY evidence Columbo has against Hamilton, this was a spectacularly stupid move on Columbo's part. Regardless of how many officers were present to witness this, the fact is that Hamilton was under arrest and had not been advised of his right against self-incrimination; meaning nothing that he said when under arrest can be used against him.
Stupidity: While discussing his arrest with Emily, Seth mentions that he didn't tell the arresting officer that he works for Kirkman. As the White House's liaison to the media, Seth has a high degree of visibility; it would extremely difficult, if not downright impossible, to keep his place of employment concealed from the police for very long in the time between his booking and arraignment and when Kendra bails him out the following day.

Stupidity: When Cyclops is arguing with Warren Worthington (Mystique in disguise), Worthington says to Cyclops "Look me in the eye and tell me that," to which Cyclops responds "It'll be my pleasure" and gets ready to shoot Worthington in the face until Professor X orders him to stand down. Cyclops is supposed to be the calm and collected field leader of the X-Men. It's pretty out of character for him to try and murder somebody, or even strike a blow, over a philosophical disagreement.
