Don't you think that by the fifth or so time that Columbo pulled that ObfuscatingStupidity nonsense that news about it would start getting around the underworld?
I'm not sure that's the sort of thing crooks say to each other. "Look out for a polite, slow-witted, absent-minded short guy with bad grooming and a glass eye, cause that's the guy who beat me."
Don't forget that most, if not all, of Columbo's cases dealt with middle- to upper-class crimes of passion or revenge. Those are not the kind of people who would get the word onto the street in the first place.
...as of the later seasons, the criminal underworld was more than well aware of who Columbo was... and they had an odd respect for him. The plots of "A Bird in the Hand" and "Columbo Likes The Nightlife" involved notorious mob bosses allowing Columbo to catch the killers rather than taking matters into their own hands. Going by this- especially after Columbo caught the killer of mob boss Joey G.'s son- organized crime may have had a strict "leave Columbo alone" policy.
It also may be that Columbo's self-assessment is correct: he actually only solves about half of his cases, and we're only seeing his (rare) triumphs.
This is sort-of reinforced by one episode in which a police official is the perpetrator. He specifically requests Columbo, thinking, we can assume, that the bumbling detective is his best bet of no one working out that he did it. That only makes sense if Columbo's reputation is more "He's a slow-witted, absent-minded bumbler, who occasionally gets lucky," and less, "He's a genius who always gets his man despite acting like a buffoon," even within the police department.
Then again, the entire point of that episode - like most episodes - is that this perp is too arrogant to see beyond what's right in front of him. Besides which, the perp's the Commissioner, or the equivalent. You could make an equally strong case that, to his bosses lower down in the hierarchy, the Lieutenant is a legend and routinely assigned to cases where his unique approach seems like the only way to solve the crime/secure a conviction.
Also, you could take some of his actions to imply that the Commissioner thinks he really has committed the perfect crime, and requests Columbo specifically in order to ensure that it didn't look like he was trying to hurt the investigation
He was an Assistant Commissioner, so he didn't even have the "excuse" of being "expected" to know anything accurate about subordinate homicide cops.
Furthermore, it's possible that the crooks aren't the only people whom Lt. Columbo obfuscates stupidity towards; whilst the men on the street may be aware that the Lieutenant's actually a crime-solving genius underneath that shabbiness, Columbo possibly turns the 'I'm just a simple-minded sap who gets lucky' attitude towards the higher-ups in order to not have to worry about, say, getting promoted to a desk job that would take him away from what he loves and is good at.
Or probably the Commissioner realised that asking for 'the second best detective on the force - not Columbo, definitely not Columbo' would be even more suspicious.
That's especially true since one of the victims was his (the Commissioner's) wife.
And of course, a Commissioner presumably wouldn't be familiar with the reputation of every single one of the officers who serves in a police force as large as the LAPD, no matter how successful; he possibly just came across Columbo's photo, thought he looked like a fool and based it on that.
It's also worth pointing out that a lot of suspects do see through his Obfuscating Stupidity after the first "Oh just one more thing" moment. On one occasion Columbo asked a suspect if he had a .25 pistol as was used in the murder. The suspect mentioned Columbo's "bumbling policeman act" and pointed out that he undoubtedly already knew the answer, whereupon Columbo just laughed and admitted that he did.
Anyway, that can be considered largely Jossed- in one of the final episodes, Columbo tells the killer that he has never failed to get his man. And he wasn't going to let him be the one who got away.
In the pilot episode, Columbo almost pushes a witness to the point of suicide and in 'A Stitch In Time' Columbo drops his act to threaten the Leonard Nimoy character in no uncertain terms. Columbo grew up in a rough neighbourhood in New York, if the Obfuscating Stupidity doesn't work, he's tough enough to try more direct methods.
Actually, the "suicide" was faked. I assume you mean the pilot movie? The supposed victim was standing in the next room, hearing the killer confess that he didn't love her, which prompted her to confess the crime.
In the episode "An Exercise in Fatality," the final, damning thing that Columbo nails the killer with is... the knot on the victims shoelace. That's... that's just really reaching. You'd never get a guy convicted on that. Heck, you couldn't even arrest a guy on it. And he didn't incriminate himself, either.
Not to mention the fact that, as pointed out on a fan website, Columbo makes the demonstration mentioning how it's how "right handed people" tie their shoes... Only the victim is clearly shown as left-handed!
Oh, there's a lot more where that one came from, believe me. Officially it's handwaved by assuming that Columbo's got the perps so nerved up by then that they just fall apart; unofficially, Word of God has cheerfully acknowledged that the show's structure owes a lot more to the classic drawing-room mystery than the strict police procedural.
Columbo himself acknowledges it from time to time (especially up against Patrick McGoohan's various villains) that he knows he's done it, and he presents his evidence that proves that he knows to the villain. however he knows that it's too weak to convict or even arrest. BUT then he adds "I'll be waiting for you to trip up".
The point of that scene was that Milo Janus admitted, in his signed statement, that he knew the victim was already in his gym clothes... which he'd not have known at all if he hadn't killed the man, as Columbo was certain- with other little bits of evidence- that Milo had killed the man long before the faked phone call, plus the knot in the lace supposedly proving that the victim had not dressed himself.
Columbo is Droopy Dog with a police badge. He'll just keep at it until the murderer goes mad and confesses just to get some peace and quiet.
And this bugs you because...?
Well, sometimes it can be a bit of a headscratcher how the bad guys consistently trip up just from annoyance when their livelihood is on the line. But to be fair, some villains are more patient with more proof against them.
As much as I liked the show, the part that always bugged me was how Columbo would gather evidence and carry it around with him as if it would still be admissable. I think it would be incredibly hard to classify something as evidence if he found it one day and didn't turn it in until three or four days later, while carrying it around in his pocket all that time.
Not that we KNOW he does so...
But he does fiddle with that stuff around the bathtub incessantly in the episode wherein the guy is murdered in his tub, touching everything at the crime scene with his bare hands. It's almost as if they're playing his incompetent behavior at a murder scene for laughs, but that wouldn't excuse it even if they were.
The episode 'Dagger of the Mind' annoys this troper with the conclusion. Sure, Columbo has planted or contrived evidence before, but the emphasis has always been on the way the villain reacted to it and showing that if he had been innocent he would not have acted in that way. But in DOTM, it is ONLY the planted evidence that gets the villain convicted.
But it was the reaction that did it. The killers completely freaked out.
Although it's also worth noting that Columbo clearly wasn't going to tell DCI Durk what he'd done if Durk hadn't asked, so if Durk had been a less honest (or inquisitive) man, it's quite possible that no one would ever have known the pearl was planted.
Why do the people always confess? Why don't they give a court case a try? In the episode with the pearl in the umbrella, it was planted evidence. he would never have gotten a case out of it.
The criminals in the show suffer from the same problem that the bad guys have in Scooby-Doo. They have to confess at the end to wrap up the plot for the audience. "I would have gotten away with it, too, if it wasn't for you pesky kids."
The court case is never shown, but modern audiences saw what happens when a rich person goes to court for murder when OJ Simpson was tried in 1995. If that level of forensic evidence didn't convict OJ, then a Columbo perp's lawyer could make mincemeat of any jury.
They didn't know it was planted. They assumed they'd made a mistake.
The murderers admitting their guilt is a way to show the remnants of dignity they managed to retain during the investigations. One of the typical ingredients of "the Columbo formula" is that the murderers are high-class, intelligent people, not some primitive, drunken oafs. Everyone knows the lieutenant wins in the end, so the villians get to make a grand exit as a way to lose graciously.
Besides in this particular story, the confession played off the play that was being preformed by the couple ("Out out damned spot").
Not every episode ends with a confession, and since we never see the inevitable court cases, it's entirely possible some of the killers end up beating the rap.
In the episode "Forgotten Lady" Columbo's proof that the killer did it was that the film she was watching broke, and if she were in the screening room as her alibi had it, why didn't she fix it quicker than she did when she returned after committing the crime. Neither Columbo nor the man desperately trying to protect her consider she might just have fallen asleep before the film broke.
True, but the episode also goes to great lengths to show that she's absolutely fascinated with these old films, the last visible symbol of her glory days, and watches them with great intensity. Also worth noting is that — unless she's an unusually heavy sleeper, which older people generally aren't — there's a good chance the abrupt cut to dead silence would wake her anyway.
Of course, if she'd had to go to the bathroom or something then it might have also accounted for the time difference...
Maybe, maybe not. As Columbo noted particularly, the film in question had a running time of one hour forty-five minutes, yet she was seen watching the end of the film some two hours and one or two minutes after the butler started it. Columbo damaged the film again to test how long it took her to repair it, and timed her at three minutes, so there's at least eleven minutes to account for, perhaps as much as fourteen. That's a long trip to the bathroom.
This particular episode is discussed often. The point of the breaking film is not really to prove that Grace killed her husband. It proves that she could have done it - by providing a time frame, just as the presence of the tree outside the window provides an escape route. Together with all the small things that cast serious doubt on the alleged suicide, and the fact that there was virtually no other suspect available, the broken film was a way to establish that she could kill him - and not really to police, either, but to Columbo himself and to the actor friend.
"Forgotten Lady" has a b-plot of Columbo missing out on his mandatory firing range testing. After repeated hounding and a threat of losing his job by Internal Affairs... Columbo hands Sgt. Burke his badge and $20, and tells him to go and take the test because "I can't hit the target". We assume this worked because he wasn't fired. How in the HELL did this work? Sgt. Burke looked nothing like Columbo, one would think, at the very least, that the officer in charge of the pistol range would have checked the badge photo, and that is assuming that the same officers who had been hounding Columbo had not been waiting there for him.
Even then, if it's canon that Columbo has a glass eye, same as Falk did, then the department should know his aim would be terrible. His superiors should also know he never carried a gun.
This is IA we are talking about (the unit that all cops hate). And Columbo, probably one of the most beloved officers on the force. So Sgt Burke goes down to the range and shows the badge, fires the gun and leaves. The officer in charge of the range says 'Yes, someone bearing the ID of Lt Columbo definitely turned up and took the test"
