In the Kennedy assassination, how did one shot pass through two people without travelling in a straight line, while another shot from the rear caused Kennedy’s head to move backwards, rather than forwards?

it would be theoretical impossible

Explanation:

a bullet is incapable of moving in a angle like that without hiting something to cause it to ricochet of of something but it wasnt a sharp torn it was like it was being guided which is impossible unless there was another shooter.

whats the question? im not quite understanding your question.

although the crusades failed to capture jerusalem, they had several major impacts on western europe. they increased the authority of the king: sometimes nobles died in battle without leaving an heir in which case the king got their land. kings passed taxes to pay for the crusades.
