Bart looked up. A robotcab was swooping over the spaceport in wild, crazy circles, dipping down, suddenly making a dart like an enraged wasp at a little nest of Lhari. They ducked and scattered; the robotcab swerved away, hovered, swooped back. This time it struck one of the Lhari grazingly with landing gear and knocked him sprawling. Bart stood with his mouth open, as if paralyzed.

Briscoe! What was he doing?

The fallen Lhari lay without moving. The robotcab moved in again, as if for the kill, buzzing viciously overhead.

Then a beam of light arced from one of the drawn energon-ray tubes. The robotcab glowed briefly red, then seemed to sag, sink together; then puddled, a slag heap of molten metal, on the glassy floor of the port. A little moan of horror came from the crowd, and Bart felt a sudden, wrenching sickness. It had been like a game, a silly game of cops and robbers, and suddenly it was as serious as melted death lying there on the spaceport.Briscoe!

Someone shoved him and said, "Come on, quit gawking, kid. They won't hold the ship all day just because some nut finds a new way to commit suicide."
