Atlantic article on Lincoln's survival

[J. Beckert]

I'm not a Doctor, but due to the reports of Lincoln's position as he was shot and the fact so much bruising and discoloration was noted on the right side of his face, I tend to believe the rather large bullet damaged both sides of his brain.

A question I have is if Lincoln had lived more than the 9 hours he did, what would the effects have been of the Doctors putting their unsanitized fingers and probes into his head have been? Infection, or something worse?
