"I and none of my comrades are guilty of any conspiracy to advocate overthrow of the United States government by force and violence. Silence might be construed as defeatism when the truth is that I am so serene in our consciousness of innocence of any crimes, that I can be imprisoned but I cannot be corrected, reformed or changed. My body can be incarcerated but my thoughts will remain free and unaffected. All human history has demonstrated that ideas, thoughts, cannot be put in prison. They can only be met in the forum of public discussion."
