When Osama was killed and his compound was raided back in 2011, they seized all his stuff as part of the raid. Now today in 2017, the CIA's released a bunch of information about images/files on his computer, which is publicly available, and it's been making the news rounds.
Though I can't link it right now, there's a brief listing of some of the weirder files in this gizmodo article:https://gizmodo.com/the-42-weirdest-mov ... 1820046327
Where, if you look at the list, there's this notable little file: [MSOMS-ANIME][MCT][nooood].mp4
Anime? And a long-running one, by the look of the number? Well, if you google MSOMS-ANIME and MCT, you'll find out that it's an Arabic fansub for Detective Conan. Episode 534 is this arc:http://www.detectiveconanworld.com/wiki ... s_the_Past
So, Osama had Detective Conan on his computer. He probably watched it.
I wonder who his favorite character was.
