Leon F. Czolgosz

THIS!

(emphasis mine)

The McKinley assassination illustrates vividly how the construction of a late nineteenth-century assassin’s life occurred within Gilded Age thought that stressed the dangerous capacities of those on the fringes of society.

Czolgosz’s life starts not with a birthday, but with the event, and works its way back, not toward an innocent, misspent youth, but toward a type. Although born in the United States, he is said to come from any number of central European countries which had recently experienced revolutionary violence. Having a father who once briefly owned a saloon makes Czolgosz a saloon dweller, surrounded by prostitutes, anarchism, tobacco and alcohol. Incapable of working because of his health, he is considered lazy and a malingerer. 

A non-practicing Roman Catholic and an itinerant day laborer, he is classified as a member of an oppressed minority religion and a working-class radical. Hitherto shy and aloof, he is now a loner. His associations frame his biography, providing his life with a meaning he could not give. Motives are ascribed to him, his secrets are revealed. The construction of an individual figure of harm out of hints, allegations, and faulty historical narratives allows for generalizations that overlook contradictions, in an effort to say something significant about the manner of the man that kills. Upon the soft ground of a quiet and dissembling killer, a tree of knowledge has been built.

Is there any better description of how Oswald is treated, historically?

Only difference is that Leon did indeed shoot President McKinley while Oswald did not shoot JFK but was framed for it.

True Vinny, but both convicted - one in by a court - one by a kangaroo court. So for our purposes it is the same difference. This is how they told the Oswald backstory.
