I think Oswald was a nutcase acting alone.
Lee Harvey Oswald was an honorable Marine who didn't do anything wrong at all in the line of duty. Gave his life for his country in fact.
You're using the pejorative term "nutcase" with all the implications of the human rights violations you fuckers impose under civil commitment, service of legal process, and involuntary hospitalization, torture, and drugging.
JFK's sister Rosemary was lobotomized on the orders of their father. Democrat murderers and extortioners with medical degrees actually cut out part of her brain in order to make her more docile and willing to submit to the family's incestuous advances.
You're a dishonorable piece of shit armed hostile enemy scum when you use the term "nutcase."
