Here are some of my favorites. I used the very scientific LOL gold standard - if the stupidity of the perp literally had me laughing out loud, it made the cut.
From the folks at Cader Books: "...In the early hours of the morning, in June 1995, Mike Cyprian ducked into a restaurant in Hammond, Louisiana, to make a phone call. He left his car engine running and his nine-foot python lounging uncaged inside. When Cyprian came out of the restaurant he saw his car in a different spot and a man running away.
From a website simply called Stupid Criminals: "...a burglar broke into a Norwegian grammar school – and solved some maths problems. Nothing was stolen in the raid on a school in Klaebu, reports Aftenposten, quoting Adresseavisen. But the intruder did take on a mathematics test intended for third grade students. And, according to local law enforcement officials, he – or she – did a good job, solving all the problems correctly.
Then there was the Ashland Kentucky man who wasn't going to be deterred when he lost his standard issue ski mask.
"...Police say Kasey Kazee entered Shamrock Liquors and attempted to rob the store. Employees were astonished that he had disguised his face by wrapping it in duct tape! The store manager chased him out with a baseball bat and an employee held him in the parking lot until police arrived. Police removed the duct tape after taking pictures, and arrested Kazee, who denied any memory of the incident."
Sometimes it's a toss-up as to whether the criminal is stupid, or just plain wacko. And at CrazyCriminals.com they found some of the wackiest:
"...In Bent Forks, Illinois, kidnappers of ice-cube magnate Worth Bohnke sent a photograph of their captive to Bohnke's family. Bohnke was seen holding up a newspaper. It was not that day's edition and, in fact, bore a prominent headline relating to Nixon's trip to China. This was pointed out to the kidnappers in a subsequent phone call. They responded by sending a new photograph showing an up-to-date newspaper. Bohnke, however, did not appear in the picture. When this, too, was refused, the kidnappers became peevish and insisted that a photograph be sent to them showing all the people over at Bohnke's house holding different issues of Success Magazine. They provided a mailing address and were immediately apprehended.
And this one's not laugh out loud funny, but I thought the guy should have gotten off for outsmarting the judge. I doubt it though.
In closing I leave you with my favorite crime joke for April Fool's. It's my favorite because it's so absurd, it's got talking animals, and most of all, because it was told to me by Willie Nelson (to be fair, he told me and four other people in the room, but still...):
