The gun Jack Ruby used to shoot Lee Harvey Oswald went for $220K in 1991. I wish I sold it!

You are entitled to your opinions and choices.Sort of inspired by, but not limited to, the ongoing events in the Middle East:
Would you deliberately seek to own a gun or tool surplused from an organization that (likely) committed human-rights abuses?
For example, there’s a lot of third-generation S&W semiautomatics coming back in and floating around places like Robinson Trading Post in decent shape. As a firearm, there’s nothing wrong with them, and most have been carried a lot and shot a little. But in the back of my head, I don’t know if I’m super-comfortable carrying something that was used as a facilitator for what I personally don’t agree with. For the same reasons, I haven’t picked up any German Russian-capture milsurps…as much as I love them (and I do), I don’t want them enough to buy them.
I don’t believe in ghosts or bloody nightmares, but I also don’t want Bull Connor’s nightstick or the Trapdoor from Wounded Knee in my karma…
What are your thoughts?
Sounds like you have a problem with war trophies brought home by our greatest generation. Nazis didn't bring them to the US...About the only thing I have had any issue with as far as ethics and firearms is I refuse to own anything that has a swastika on it...
Likewise. I once came into a Colt OP that had been a suicide gun. I was somewhat bothered by having it, and did not keep it very long. Also had a .22 rifle which had been used in a local slaughterhouse for a long time. I did not keep it long either. It gave me the creeps. The most beat-up gun I ever saw.I bought a pawnshop PPK that turned out to be a WW2 SS-issued gun. Didn't bother me, I even shot it a few times before I sold it.
I am pretty sure I lost at least some relatives to the Nazi occupation in WW2.
History is history. I also have a WW2 1911a1 that was in the European theater.
I did pass on buying an Ed Brown one time that had been a suicide gun. The finish was scratched at the muzzle from the prior owners teeth and the shop wanted way too much considering the finish dama
My Dad served in the South Pacific on a Destroyer Escort. His stories were few and far between.Being a US Military historian and collector Ive had many many assorted weapons from WWI and WWII. Being in a group that was hired by US Navy and USAF to display our collections at air shows we met countless WWII Veterans. I wish I/ we had recorded our conversations with these Veterans as they are all gone. Weapons cant talk but Veterans can. nuf sed
Look at the auctions and see how much guns bring that were used by criminals / outlaws in this country and others. People are mystified by even the opportunity of owning a gun that a Bonnie or Clyde or maybe Billy the Kid, etc once owned regardless of who was the victim of their actions.Your humanizing a inanimate object.
You want something go get it, I would be more concerned with condition not its possible use.
Now if it came with serious provenance that it was owned by a certain real bad person, that is another category. Your conscience will have to be your guide!
