The tedious conspiracy theorists will be out in force ad infinitum on this one, but there are a number of questions that demand answers, including how he got there and how he got a shot in. The fact he was killed so shortly after firing at Trump shows that he can’t have been obscured for every sniper there.
The problem with the human mind (in the context of conspiracy theories) is the pleasure it takes in theorising on matters over which it has scant or no evidence, in the pursuit of vindication. It’s the same reason we like to gamble, another pursuit which is frequently based on guesswork. The truth is, even if their theories are occasionally right, it’s usually not based on anything of merit; they’ve just picked the right number on a roulette wheel, but it doesn’t stop some folk from basing their entire being on being right about a particular theory, because it makes them feel wise, intelligent and more perceptive than others, when in actual fact they are just guessing, and occasionally being right, conspicuously forgetting all those times they were hopelessly wrong.
We all do it to sone extent or another btw, it’s just some take it to an absurd and dangerous level.
