That would have made sense with what they knew about Malcolm - an unarmed, assumed non-combatant - but that was not what Malcolm did. He ran after Raylan and Tim, staying behind them for the time being. However, when the suspect ran out of ground, he pulled a gun out of his pocket and spun on the officers.

"DON'T SHOOT!" Malcolm shouted from the back at literally everyone, holding out a hand, then holding up both hands. "Don't shoot!" he said again, more firmly, stepping in between the marshalls and the suspect.

He stepped towards the suspect, keeping his hands non-threateningly in the air.

"You've been busy," he noted, his tone deliberate, keeping his eyes on the man. "Trying to purge your pain." He studied the man's face. "And you've had a LOT of pain."
