How could anyone not feel sorry for her...

Knowing the real history mitigates my sympathy a bit. Whether or not the formalities of law were observed, her sentence was just.

The movie was kind to her. She failed to identify Powell and organised the shooting irons. That's prison at the least

How could anyone not feel sorry for the country. This movie is a further example of the fact that dirty politics, sleazebag politicians and a corrupt few have and always will be the ones who control this country. A bought off system with a predetermined result is nothing new. 100 years after the formation or 240 years- it makes no difference. The system is corrupt and may be subverted to the interests of the few to the detriment of the interests of the many.

Justice for all- more like justice for all the rich and powerful- garbage for everybody else.

Didn't feel sorry for her at all, but yeah if that's how the trial actually went then it shows how crooked the US government was (and is). Still, no sympathy for supporters of slavery. I noticed that wasn't mentioned at all in the whole film; it was as if the north and south were fighting just because northerners and southerners didn't like each other for the fact that they were northerners and southerners. These Confederate sympathizers were slime working for a rancid cause. Whether they were involved in the killing of Lincoln or not, they were trash people.

the movie was a bit of propaganda, not much more :

she was well hung :

she denied knowing powell, who stabbed seward and others within the household & who she knew well, when he showed up inconveniently at her door with a pick-axe while the investigators were at her house after the investigation.

the assassins were using her house while john surratt was nowhere near DC on the day of the assassination. she spent much time in conversations with booth before the assassination. her road-house tavern was the first place booth went to to pick up an eyeglass and weapons in his flight after the assassination. this same road-house in surrattsville was where dr. mudd arranged a meeting between john surratt & booth.

"Powell posed as a Baptist preacher and stayed at the boarding house for three days in March 1865.[93][98] David Herold also called at the home several times.[91][97]

after a search of the house, the agents found in Mary's room a picture of Booth, hidden behind another photograph, pictures of Confederate leaders including Jefferson Davis, a pistol, a mold for making bullets, and percussion caps.[120][123][125]

As part of the plot to kidnap Lincoln in March 1865, John, Atzerodt, and Herold hid two Spencer carbines, ammunition, and some other supplies at the Surratt tavern in Surrattsville.[88][99][100] On April 11, Mary Surratt rented a carriage and drove to the Surratt tavern.[101] She said that she made the trip to collect a debt owed her by a former neighbor.[101] However, according to her tenant, John Lloyd, Surratt told him to get the "shooting irons" ready to be picked up.[88][102] On April 14, Surratt said that she would once again visit the family tavern in Surrattsville to collect a debt.[88][103] Shortly before she left the city, Booth visited the boarding house and spoke privately with her.[88][104][105] He gave her a package, later found to contain binoculars, for Lloyd to pick up later that evening.[88][104][105] Surratt did so and, according to Lloyd, again told Lloyd to have the "shooting irons" ready for pickup and handed him a wrapped package from Booth.[88][99][106][107] "
