The captain studied Celtrics' face for possible irony; after all, watchbird had been in the papers for months. But then he remembered that Celtrics, like his sidekicks, rarely bothered to turn past the sports pages.
"Well," the captain said, trying to remember what he had read in the Sunday supplements, "these scientists were working on criminology. They were studying murderers, to find out what made them tick. So they found that murderers throw out a different sort of brain wave from ordinary people. And their glands act funny, too. All this happens when they're about to commit a murder. So these scientists worked out a special machine to flash red or something when these brain waves turned on."
"Scientists," Celtrics said bitterly.
"Well, after the scientists had this machine, they didn't know what to do with it. It was too big to move around, and murderers didn't drop in often enough to make it flash. So they built it into a smaller unit and tried it out in a few police stations. I think they tried one upstate. But it didn't work so good. You couldn't get to the crime in time. That's why they built the watchbirds."
"I don't think they'll stop no criminals," one of the policemen insisted.
"They sure will. I read the test results. They can smell him out before he commits a crime. And when they reach him, they give him a powerful shock or something. It'll stop him."
"You closing up Homicide, Captain?" Celtrics asked.
"Nope," the captain said. "I'm leaving a skeleton crew in until we see how these birds do."
"Hah," Celtrics said. "Skeleton crew. That's funny."
