question:  Which is not a reason the captain does not want to create a police force?
context: Still, it had an appeal Keith Ellason knew he couldn't deny, a newsman's joy of the clean beat, a planetary system far afield, a closeup view of the universe, history in the making. The decision of Interstellar was that the colonists started a revolution far out in space, that it was fanned by the ignorance of Captain Sessions in dealing with such matters. "We have conquered the problem of small groups in space—witness the discovery of Antheon, for example—but when there are large groups, control is more difficult." It ended with passengers engaging in open warfare with each other and the crew. "No weapons were allowed on the ship, but you must remember the colonists were selected for their intelligence and resourcefulness. "Assuming no accident in space," Phipps said, "it was a wrong decision. We don't think anything is going to happen, but if it does, we want to get an impersonal, unprejudiced view. Basically, it was an instrument which would open distant vistas to colonization, reducing the shoulder-to-shoulder pressure of a crowded solar system. A space-borne metropolis, it would be the home for three thousand persons outward bound, only the crew on the return trip. The captain's briefing room was crowded, the air was heavy with the breathing of so many men, and the ventilators could not quite clear the air of tobacco smoke that drifted aimlessly here and there before it was caught and whisked away. To make it easier for you, I suggest you think of this journey strictly from the observer viewpoint. In Ellason's mind the incident, though insignificant from the standpoint of the ship as a whole, could very well be the cause of dissension later on. He said it was significant that all en route had passed stability tests, and that it was to the ship's discredit that someone with criminal tendencies should have been permitted aboard.
