When Danny gets shot at the end of the film, his paper flies out of his hand. But the very next shot of him shows that the paper is still in his hand being held over his head while he falls backwards. In one of the following shots the paper is back on the floor, but it's on the opposite side it should have been when it flew out of his hand. It's all shown in slow motion and it's very obvious.
At the end, when Danny is heard quoting from the paper he wrote for Dr. Sweeney, the quote which begins "We are not enemies, but friends..." is the closing paragraph from President Abraham Lincoln's first Inaugural Address on the 4th of March 1861.
