"It's all up to the deAngelis operators. They're the kingpins, they make the system work. Not Simon deAngelis who invented it, or the technicians who install it, or the Police Commissioner who takes the results to City Hall. The operators make it or break it. Sure, they have rules to follow--if they want. But a good operator ignores the rules, and a bad operator goes by the book, and he's still no damn good. It's just like radar was sixty, seventy years ago. Some got the knack, some don't." "Then the deAngelis doesn't do the job," said the cub. "Certainly it does," the older man said. "Nothing's perfect. It gives the police the jump on a lot of crime. Premeditated murder for one. The average citizen can't kill anyone unless he's mad enough, and if he's mad enough, he registers on the deAngelis. And ordinary robbers get caught; their plans don't go just right, or they fight among themselves. Or, if they just don't like society--a good deAngelis operator can tell quite a bit if he gets a reading at the wrong time of day or night, or in the wrong part of town." "But what about the sweet old lady who registers sixty-five and then goes berserk?" "That's where your operator really comes in. Usually that kind of a reading comes too late. Grandma's swinging the knife at the same time the light goes on in the station house. But if she waits to swing, or builds herself up to it, then she may be stopped. "You know those poor operators are supposed to log any reading over sixty, and report downtown with anything over eighty. Sure they are! If they logged everything over sixty they'd have writer's cramp the first hour they were on watch. And believe me, Sonny, any operator who reported downtown on every reading over eighty would be back pounding a beat before the end of his first day. They just do the best they can, and you'd be surprised at how good that can be." * * * * * The old man woke up, but kept his eyes closed. He was afraid. It was too quiet, and the room was clammy with an early morning chill. He opened his eyelids a crack and looked at the window. Still dark outside. He lay there trembling and brought his elbows in tight to his body. He was going to have the shakes; he knew he'd have the shakes and it was still too early. Too early. He looked at the clock. It was only a quarter after five. Too early for the bars to be open. He covered his eyes with his hands and tried to think. It was no use; he couldn't think. He sobbed. He was afraid to move. He knew he had to have a drink, and he knew if he got up he'd be sick. "Oh Lord!" he breathed.
