question:  What advantage did the rebels have over the Venus Consolidated police?
context: And once it grows, someone with a tyrant mind is going to try to use it as a weapon if he can— [Transcriber's Note: This etext was produced from Astounding Science-Fiction April 1942. This was the administrative heart of Venus City. As head of the Venus Consolidated Research Organization, he was in large part responsible for the prosperity of this vigorous, young world. Venus Consolidated had built up this city and practically everything else that amounted to anything on this planet. True, there had been others, pioneers, before the company came, who objected to the expansion of the monopolistic control. But, if they could not realize that the company's regime served the best interests of the planet, they would just have to suffer the consequences of their own ignorance. Venus Consolidated police had only powers of arrest. This walk was part of a regular routine of physical exercise that kept his body hard and resilient in spite of long hours spent in the laboratory. He was making that walk in precisely seven minutes, four and four-fifths seconds. Brian Hanson, Chief of Research for Venus Consolidated, as dignified as possible in a damp bathrobe, glared out through the bars at a slightly bewildered Pete Brent. If sending that damn blonde to my apartment and getting me arrested is your idea of a joke—" "But, my gosh, I didn't send anybody, chief. They're about the oldest family on Venus. Police have been after her for months; she's a rebel and she's sure been raising plenty of hell around here. All I want is to get out of here—" "Gotcha, chief," Brent whispered understandingly. I don't care if you are—" Brian's eyes almost popped out as he saw a gloved hand reach around the guard's neck and jam a rag over his nose and mouth. Swift shadows moved expertly before his astonished gaze. Another guard was caught and silenced as he came around the end of the corridor.
