 Why is Lane so child-like?
Raging , Trooper Lane hovered three thousand feet above Tammany Square. The humming paragrav-paks embedded beneath his shoulder blades held him motionless above Newyork's three administrative towers. They don't teach them about their own city, that they'll be fighting for. From seven years old up, Troopers have too much to learn about fighting. Two black paragrav-boats whirred along the translucent underside of Newyork's anti-missile force-shield, the Shell. Lane somersaulted. Cybrain had taken charge of his motor nerves. Lane dropped lightly to the floor, inside the room, in battle-crouch. "Lashing police with his vibray," said the announcer, "Lane broke through the cordon surrounding Manhattan Armory. Tammany Hall has warned that this man is extremely dangerous. Citizens are cautioned to keep clear of him. Lane is an insane killer. A built-in electronic brain controls his reflexes—" "At ease with that jazz," said Lane, and a sheathed finger snapped out. Lane's mailed hand snapped open a pouch at his belt. The force-bomb "exploded"—swelled or inflated, really, but with the speed of a blast. It shaded the view from his window and re-entered the tower wall just below. Orange or green is the action. This is an embassy, if you know what that means." Sure, I've heard of it—you gotta go by spaceship. Look, Lane, holding me is no good. But also the road to the return to city-states. Anarchy."
 Lane was never given a proper education, only fighting instruction.
 All men are child-like.  Lane was never given a proper education, only fighting instruction.  Lane is controlled by the Cybrain. His own brain never had the chance to develop properly.  Lane has been a Trooper since he was seven years old.
