For most people, the shock and horror at the assassination of President Kennedy were doubly compounded by the subsequent murder of the alleged assassin.

Although assassination of the President of the United States violated no Federal law, to threaten the life of the President of the United States is a punishable Federal offense, under Title 18 of the United States Code, Chapter 41.
