CISRA Puzzle Competition 2012 - Hints

1B. Who Really Shot First?

• These mixed up utterances share a common theme - a strong theme throughout this puzzle.
• Each line is two quotes. Each line provides two new sets of information. Oh, and to be more direct: who shot first?
• Extract the errant letters, and the letters in the same positions from the other quote. Oh, and even more directorly: who "shot" first?
