Source/link? I'm not saying you're wrong, but I've heard a lot of crazy stories about what's supposedly on the darkweb, but a lot of it seems to be just that: stories.
You won’t do the work to back your own claim? Ok, well add me to the list of people calling bullshit then. Besides, who, but s cannibal would know the different between a leg of veal pork, and a... leg? Occam’s Razor says the books are jokes, pranks, or scams, and/or that you’re bullshitting. In the absence of evidence at least.
Well for starters you can try checking the watchpeopledie subreddit and look for human stew.
I don’t work for free, I’m barely giving a fuck away.
If you can’t back up an extraordinary claim, and “lots of cookbooks for cannibals” is pretty extraordinary, don’t make claims. If you don’t give a duck, are lazy, whatever, don’t waste your time making claims. It’s really simple, unless you’re wasting everyone’s time for amusement, and there’s a name for that.
The dark web isn't a cave, it's part of the internet. The user experience of using Tor browser is basically "slow Firefox with unpronounceable URLs". You could easily link something if you've seen it.
The fact that you can't copy/paste a URL here makes me think that you probably haven't seen this. It's more likely that you just heard a Reddit rumor about cannibals on the dark web and decided to repeat that rumor here without thinking through the reliability of your source.
But hey, you can prove me wrong with a simple link.
It may be location dependant, but IMHO any corpse in a morgue would be full of preserving chemicals to ensure it'd be "presentable" for the funeral, and thus inedible.
Morgues absolutely do not embalm, they refrigerate. A body in a morgue is either unidentified, awaiting autopsy/examination, or yet to be claimed. None of those categories permit embalming, and in any case, morgues are not funeral homes.
Edit: the other object are interesting: credit card, spy camera...
