Not sure why anyone in their right mind would want to be a cop.
There was only one catch and that was Catch-22, which specified that a concern for one's own safety in the face of dangers that were real and immediate was the process of a rational mind. Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn't, but if he was sane, he had to fly them. If he flew them, he was crazy and didn't have to; but if he didn't want to, he was sane and had to. Yossarian was moved very deeply by the absolute simplicity of this clause of Catch-22 and let out a respectful whistle.
I'm not losing any sleep knowing some crazy m'fer that was throwing rocks and people and police ended up shot and killed. Big whoop.
"There must have been a reason," Yossarian persisted, pounding his fist into his hand. "They couldn't just barge in here and chase everyone out."
"No reason," wailed the old woman. "No reason."
"What right did they have?"
"Catch-22."
"What?" Yossarian froze in his tracks with fear and alarm and felt his whole body begin to tingle. "What did you say?"
"Catch-22," the old woman repeated, rocking her head up and down. "Catch-22. Catch-22 says they have a right to do anything we can't stop them from doing."
"What the hell are you talking about?" Yossarian shouted at her in bewildered, furious protest. "How did you know it was Catch-22? Who the hell told you it was Catch-22?"
"The soldiers with the hard white hats a clubs. The girls were crying. 'Did we do anything wrong?' they said. The men said no and pushed them away out the door with the ends of their clubs. 'Then why are you chasing us out?' the girls said. 'Catch-22,' the men said. 'What right do you have?' the girls said. 'Catch-22,' the men said. All they kept saying was 'Catch-22, Catch-22.' What does it mean, Catch-22? What is Catch-22?"
"Didn't they show it to you?" Yossarian demanded, stamping about in ager and distress. "Didn't you even make them read it?"
"They don't have to show us Catch-22," the old woman answered. "The law says they don't have to."
"What law says they don't have to?"
"Catch-22."
