Why is Mary Surratt Guilty?

Mary Surratt was found guilty primarily due to her alleged involvement in the conspiracy to assassinate President Abraham Lincoln. As the owner of the boarding house where John Wilkes Booth and other conspirators met, she was accused of facilitating their plans. Additionally, her connections to Booth and her knowledge of the conspiracy, coupled with the trial's politically charged atmosphere, contributed to her conviction, despite the lack of direct evidence tying her to the act of assassination itself. Her execution in July 1865 remains controversial, as many believe she was unfairly tried and punished.
