"Stop yelling, boy—you matched the complaint, and now you're going to learn what happens when you talk back to me."
Sergeant Frank Collins forced nineteen-year-old Ethan Miller's right arm higher behind his back until Ethan's cheek pressed against the grass beside the concrete walkway. The paper coffee cup Ethan had been holding less than two minutes earlier lay overturned near the curb, brown liquid spreading across the pavement while stunned families stared from beneath the shade trees of Arlington's Brookfield Park.
Ethan's gray hooded sweatshirt was streaked with grass. His chest rose quickly. He was scared, angry, and trying desperately not to make a movement the officer could describe as resistance.
"I didn't do anything," Ethan gasped. "I was drinking coffee."
Collins tightened his grip. "Keep running your mouth."
A woman standing beside a stroller covered her lips with one hand. Her toddler stared silently from beneath the stroller canopy. Three people had their phones raised. One man near a green park bench was recording from less than fifteen feet away.
Collins noticed. He looked toward the witnesses. "Back up. Police business." Nobody moved much.
Ethan turned his face slightly toward the crowd. "You slammed me for drinking coffee in a park because you thought nobody here would stop you."
Collins's jaw clenched. He yanked Ethan's arm higher. "One more word and I'll stack resisting, disorderly conduct, and whatever else I need to bury you."
Ethan winced. Then his eyes shifted toward the road beyond the trees. A black SUV had just turned into the park entrance. Ethan saw it before Collins did. His breathing changed.
Collins interpreted it as fear. "What? Nothing clever to say now?"
Ethan stared toward the approaching vehicle. Then he said quietly: "Keep performing for those cameras. Because the man getting out of that truck runs the FBI office you're about to answer to."
Collins laughed. It was loud enough for the crowd to hear. "Sure he does."
