This was to be a peaceful show of unity before the planetary rulers, and thus the judges passed unmolested through the crowd.
They emerged onto Liberation Square, less than five hundred metres from the palace gates and the line of genuine Adeptus Arbites. Directly ahead of them, Vedden could see the statue of the Emperor and six people shouting at the crowd through bullhorns.
Vedden did not listen to the words.
'Wedge formation,' he hissed, and his men formed into an arrowhead shape, three either side of him with their shields facing outwards, and three men in the centre with their shotguns cocked and loaded.
'Let's go.'
They moved off, pushing a path towards the statue.
Virgil Ortega scanned the crowd, eyes alert for trouble, despite the avowed intentions of the speakers on the Emperor's statue. He'd just received check-ins from each of his squads and thus far, all was well.
A flash of movement and a ripple of shouting through the crowd caught his attention as he saw a group of judges emerge from the approach street ahead and to his left. He frowned in puzzlement.
Whose squad was that and what the hell were they doing out of position?
Ortega cycled through his vox frequencies, checking every squad's location and coming up with everyone in their proper place. Had the chief put more squads on the ground?
Instantly, he discounted that possibility. The chief was not so idiotic as to put uniformed troops in the square and not tell him.
A shiver passed down his spine, despite the day's heat, as he watched the unknown judges form a wedge and begin pushing their way through the crowd.
His eyes traced where their route would take them.
'Hell and damnation, no!'
'Sir,' inquired Collix.
Virgil Ortega dropped his shield and ran back to where the Rhinos rambled throatily. He jumped on the front bull-bars of the nearest and lifted his helmet visor, scrambling up onto its roof.
The judge inside popped the top hatch and poked his head out.
'Sir?'
'Give me the damn loud-hailer. Now!'
The judge retreated into the Rhino, emerging seconds later with the loud-hailer handset which Ortega snatched from his outstretched hand.
He flicked the talk button and shouted, 'Attention. Attention. This is Judge Virgil Ortega, you people on the statue, get down now!'
The Rhino's loud-hailer was easily able to carry across the square, but his plea was ignored. Scattered shouts and jeers greeted his words and a few inaudible replies were hollered from the statue's plinth.
Damn them! Didn't these fools realise he was trying to save their lives?
He tossed the handset back and jumped from the Rhino's roof. Running back to the judges' line, he grabbed Collix and a handful of judges.
'Judges, form wedge on me. We have to get to that statue quickly. Come on.'
With practiced precision, the judges formed a wedge around Ortega, the twin of the one already within the crowd. Ortega knew he had to get to the statue first.
But even as they set off, he could see they would be too late.
The shouts surrounding their advance through the crowd were getting louder, but Vedden ignored them. The statue of the Emperor was their objective and anyone who wasn't quick enough to get out of their way was brutally clubbed aside. A few kicks and punches were aimed at them, but their solid shields made fearsome bludgeoning weapons and soon most people were getting out of their way rather than defy them.
Vedden heard a rough voice ordering the speakers to get down from the statue, and saw a judge commander standing on the back of a Rhino shouting and waving his arms frantically.
But the cretins on the podium ignored him. They were making it too easy.
Like a pebble thrown in a pond, angry ripples of their advance were spreading outwards, as more people began stumbling back, braised and bloody. A threatening rumbling spread as news of the judges' aggressive tactics began filtering through the crowd. The people on the statue now saw Vedden and his men approaching, and turned their attention to them.
Cries of abuse and self-righteousness were hurled at them, as the speakers denounced the criminal violence employed by the lackeys of a morally bankrupt administration.
The mood of the crowd had turned ugly, but it didn't matter, they were almost there.
A ring of heavy-set men surrounded the statue's base and there was no mistaking their threat. Vedden stopped as a wiry man with a long beard addressed him directly from the podium.
'Brother! We are doing no harm, we have assembled peacefully. Let us continue and I guarantee there will be no trouble.'
Vedden did not answer him. He unlimbered his shotgun. He racked the slide.
And in full view of thousands of demonstrators, shot the man dead.
Ortega saw the leader of the unknown judges unsheath his shotgun and pull the trigger as though in slow motion.
The sluggish echo of the weapon's discharge washed over him as he saw the man on the podium hurled languidly backwards against the alabaster effigy of the Emperor of Mankind. His blood splashed up the statue's thigh as he toppled over a carven foot and tumbled to the ground. His skull burst open with a sickening, wet crack on the cobbles of Liberation Square and, as his brains emptied from his cranium, time snapped back into focus.
The judges in the killer's shield wall crouched, bracing their shields on their thighs as the ones in the centre of the wedge took aim at the stunned survivors on the statue's podium. A volley of automatic shotgun fire blasted the remaining speakers from the Emperor's feet and Virgil knew that they would be lucky to live through this.
Mykola Shonai squeezed her eyes shut as she heard the echo of the shotgun blast and saw the man fall. That was it, she knew. There would be no coming back from this.
A final line had just been crossed and nothing would ever be the same again.
Jenna Sharben surged to her feet as the man toppled from the statue's plinth, a shout of denial on her lips. She faced Barzano, her face full of mute appeal, dumbfounded at what had just occurred. Barzano chewed his bottom lip, his fists curled.
She made to move past him, but he grabbed her arm with a strength that surprised her and his previously bland features took on a steely hardness. He shook his head.
He dragged his eyes from hers and scanned the crowd, taking in the tactical situation in Liberation Square in an instant. He turned to Sergeant Learchus.
'Sergeant, I need you down there.'
Gone was Barzano's jocular tone and in its place was a full, rich voice, obviously used to giving orders and having them obeyed.
Learchus had seen all that Barzano had, and understood the situation as well as he.
'What would you have me do?' asked the massive Space Marine.
'Whatever you can.'
Vedden fired another volley of shotgun blasts into the crowd, relishing the screams of pain and terror he was causing. Those nearest to him frantically pushed away from the slaughter, but the press of bodies in the square was preventing them from getting out of the way quick enough.
Too bad for them, thought Vedden, pulling the trigger again.
Damn, but it felt good to be killing something, even if it was just dumb civilians. He'd wanted to have a crack at the judges themselves, but his orders were specific: only civilians. Kill as many as you can, capture one of their leaders and get back.
It made sense to capture one of the leaders. The Workers' Collective would demand that leader's release from the Arbites precinct house and the judges would truthfully claim that they were not holding anyone. Of course they would not be believed and it would be taken as another sign of the corruption rife within the planetary administration. It was perfect.
