Did the US assassinate JFK?

I haven't done a lot of research into this one because whenever I try to look into it all the sources are either complete wackos I wouldn't trust to tell me much of anything, or people clearly just repeating the state narrative. I used to blankly dismiss the idea in my Libshit days and I would like to examine it more in depth. So I would very much appreciate opinions and good sources to read up on it.
