premise: A man in a blue t-shirt with writing on it is speaking into a handheld system, and another man is sitting beside him with a megaphone in back of him. hypothesis: Two guys about to break out of jail.
contradiction: The two men would not be speaking into a handheld system and have a megaphone if they are also attempting to break out of jail. Prisoners would not have access to a handheld system/megaphone, and they would not be announcing their jailbreak.
