That's the only legal loophole I can see. But the passenger it appears only failed to comply after being told a computer decided he was to be offloaded. Not to mention minimum force required to meet the objective. As others have said, plenty more ways to have reached that objective. How many were tried before someone "jumped the gun"? Sorry, Chicago airport police don't have guns 😂
