What notable aspects are associated with Garfield's assassination?

• A. Mental insanity defense, first air conditioner, first metal detector
• B. Mental insanity defense only
• C. First use of a radio in a presidential assassination
• D. Garfield survived the attack

Answer: (A)

Garfield’s assassination is remembered for two key milestones in American history: the use of the insanity defense in the defendant’s trial and the attempt to locate the bullet with an early metal detector. The insanity defense marked a major moment in judicial history, as Guiteau’s lawyers argued that he was not responsible for his actions due to mental illness. The metal detector episode, led by Alexander Graham Bell team, stands as one of the first efforts to use technology to locate a bullet in a living patient, illustrating an early intersection of medical need and investigative science. Garfield did not survive the attack, so surviving the incident isn’t part of what this event is known for. The other options mention elements (like a radio or an air conditioner) that aren’t tied to this event, which is why the two well-documented aspects—insanity defense and the metal detector—are the strongest associations.
