No, the problem is that I know too much about US intelligence operations outside of the Kennedy assassination.
I’ve read biographies on Allan Dulles, James Angelton, and various books about covert operations abroad. I’ve studied COINTELPRO, MKULTRA, CHAOS, etc.
It’s not just my political biases but also the pattern of behavior of our national security state which leads me to believe it’s plausible that they were complicit in the Kennedy assassination.
But your problem here is that almost all of that was approved or ordered by Presidents (Cointelpro was done by the FBI). E.g., the covert war on Cuba essentially ended after JFK was killed. Why do you think that happened? Did you read the Weiner book on the CIA? The nasty stuff was on orders of Presidents. Ike, JFK, Nixon. I think that's why leftists like I.F. Stone and Chomsky, and a few others, didn't and don't believe in the "CIA did it" conspiracy. They knew who JFK was and they knew that many of the awful things the CIA did was on orders. It wasn't a rogue agency.
The idea that the CIA did bad things A, B, and C (and they did terrible things) means they killed their own President and then others went along to cover it up is preposterous. You are not talking about the national security state. You are talking about almost the entire government and news media.
You don't actually think someone like Hersh would cover this up? The same people who exposed the abuses you mentioned have covered up for the murder of JFK? That's completely illogical.
