General Patton realized the USA took the wrong side in WWII. When he returned to the USA after the war, he was going to be an outspoken critic of the war and plant in the mind of every White man in America that maybe the USA took the wrong side in World War II. That's precisely why they had to kill him. They drove a huge Truck into his vehicle that he was being escorted in. They crushed his body. He still tried to live in the hospital. Maybe they killed him in the hospital because getting his body smashed was not even enough to take him out. Keep in mind that back then vehicles were made of hard steel with no bumpers or Styrofoam or airbags.
