He jogged the two blocks. Whatever was happening might end without him.

A young, bemused face turned at Jerryberry's hail. "Excuse me, sir. Can you tell me how this started?"

"Nope. Sony. I just got here," said the young man, and he strolled off. He would be edited from the tape. But other heads were turning, noticing the arrival of- A lean young man with an open, curious, friendly face, topped by red-blond hair curly as cotton. A tiny mike at his lips, a small plug in one ear, a coin purse at his belt. In his hands, a heavy gyrostabilized teevee camera equipped with a directional mike.

A newstaper. One pair of eyes turned for an instant too long. The woman swung her purse. The policeman's arm came up too late to block the purse, which bounced solidly off his head. Something heavy in that purse.

The policeman dropped.

Things happened very fast.

Jerryberry talked rapidly to himself while he panned the camera. Occasional questions in his earpiece did not interrupt the flow of his report, though they guided it. The gyrostabiized camera felt like a living thing in his hands. It followed the woman with the heavy purse as she pushed her way through the crowd, shot Jerryberry a venomous look, and ran for a displacement booth. It watched someone break a jeweler's window, snatch up a handful of random jewelry, and run. The directional mike picked up the scream of an alarm.

The police officer was still down.

Jerryberry went to help him. It occurred to him that of those present, the policeman was most likely to know what had been going on. The voice in his earpiece told him that others were on their way, even as his eye found them leaving the booths: faces he knew on men carrying cameras like his own. He knelt beside the policeman.

"Officer, can you tell me what happened?"

The uniformed man looked up with hurt, bewildered eyes. He said something that the directional mike picked up, but Jerryberry's ears lost it in the crowd noise. He heard it later on the news. "Where's my hat?"

Jerryberry repeated, "What happened here?" while a dozen C.B.A. men around him were interviewing the crowd, and police were pouring out of the displacement booths. The flow of blue uniforms looked like far more than they were. They had to use their shock-sticks to get through the crowd.

Some of the spectators-shoppers-strollers had decided to leave. A wise decision, but impractical. The nearest booths could not be used at all. They held passengers cased in glass, each trying to get his door open against the press of the mob. Every few seconds one would give up and flick out, and another trapped passenger would be pushing at the door.

For blocks around, there was no way to get into a displacement booth. As fast as anyone left a booth, someone else would flick in. Most were nondescript citizens who came to gape. A few carried big cardboard rectangles carelessly printed in fluorescent colors, often with the paint still wet. A different few, nondescript otherwise, had rocks in their pockets.

For Jerryberry, kneeling above the felled policeman and trying to get audible sense out of him, it all seemed to explode. He looked up, and it was a riot.

"It's a riot," he said, awed. The directional mike picked it up.

The crowd surged, and he was moving. He looked back, trying to see if the policeman had gained his feet. If he hadn't, he could be hurt.. but the crowd surged away. In this mob there was no conservation of matter; there were sources and sinks in it, and today all the sinks were sources. The flow had to go somewhere.

A young woman pushed herself close to Jerryberry. Her eyes were wide; her hair was wild. A kind of rage, a kind of joy, made her face a battlefield. "Legalize direct-current stimulus!" she screamed at him. She lunged and caught the snout of Jerryberry's camera and mike and pulled it around to face her. "Legalize wireheading!"

Jerryberry wrenched the camera free. He turned it toward the big display window in Penney's. The glass was gone. Men crawled in the display window, looting. Jerryberry held the camera high, taking pictures of them over the bobbing heads. He had the scene for a moment-and then three signs shot up in front of the camera. One said ""TANSTAAFL." and one bore a mushroom cloud and the words 'POWER CORRUPTS!" and Jerryberry never read the third because the crowd surged again and he had to scramble to keep his feet. There were men and women and children being trampled here. He could be one of them.

How had it happened? He'd seen it all, but he didn't understand.

He tried to keep the camera over his head. He got a big brawny hairy type carrying a stack of teevees under his arm, half a dozen twenty-inch sets almost an inch thick. The thief saw the camera facing him and the solenm face beneath, and he roared and lunged toward Jerryberry.

Jerryberry abruptly realized that there were people here who would not want to be photographed. The big man had dropped his teevees and was plowing toward him with murder on his face. Jerryberry had to drop his camera to get away. When he looked back, the big man was smashing the camera against a lamp post.

Idiot. The scene was on tape now, in the C.B.A. buildings in Los Angeles and in Denver.

The riot splashed outward. Jerryberry perforce went with it. He concentrated on keeping his feet.

The explosive growth of the mall riot has taken enforcement agencies by surprise. Police have managed to hold the perimeter and are letting people through the lines, but necessarily in small numbers.

The screen showed people being filtered through a police blockade, one at a time. They looked tired, stunned. One had two pockets full of stolen wristwatches. He did not protest when they confiscated the watches and led him away. A blank-eyed girl maintained a death grip on a rough wooden stick glued to a cardboard rectangle. The cardboard was crumpled and torn, the Day-Glo colors smeared.

Meanwhile all displacement booths in the area have been shut down from outside. The enclosed area includes fourteen city blocks. Viewers are warned away from the following areas.. . These scenes were taken by C.B.A. helicopter.

Most of the street lights were out. Those left cast monstrous shadows through the mall. Orange flames flickered in the windows of a furniture store. Diminutive figures, angered by spotlights in the helicopter, pointed and shouted silently into the camera viewpoint. The deep, earnest voice went on: We are getting no transmissions from inside the affected area. A dozen C.B.A. newsmen and an undisclosed number of police in the area have not been heard from….

Many of the rioters are armed. A C.B.A. helicopter was shot down early today but was able to crash-land beyond the perimeter. Close shot of a helicopter smashed against a brick wall. Two men being carried out on stretchers, in obvious haste. The source of weapons is not known. Police conjecture that they may have been looted from Kerr's Sport Shop, which has a branch in the mall.

How did it all start?

The square brown face looking out of the tridee screen was known throughout the English-speaking world. When news was good, that wide mouth would smile enormously, the filter cigarette in the middle of it smoldering delicately between white front teeth. It was not smiling now. That expression was more earnest; it was shaken.

Jerryberry Jansen looked back with no expression at all.

He had thrown away his camera and seen it destroyed. He had dropped his coin purse and ear mike into a trash can. Not being a newsman was a good idea during the mall riot. Now, an hour after the police had let him through, he was still wandering aimlessly. He had no goal. Almost, he had thrown away his identity.

He stood in front of an appliance-store window, watching teevee. The deep, precise voice of Wash Evans was audible through the glass-barely.
