In Queens, the small things haven’t felt small: a car with no plates that never moves but always eats a parking spot, mopeds slicing down the sidewalk as parents yank strollers to safety, music that doesn’t quit (even when the block is begging for sleep), sidewalks bottlenecked by encampments. Even as violent crime fell to record lows, day-to-day frictions mounted. City numbers tell the story: Since 2017, panhandling complaints soared nearly 2,800 percent, calls about homeless encampments rose more than 500 percent, noise complaints nearly doubled, illegal-parking complaints more than doubled. The unspoken feeling across the borough was that unless it was violent crime, help might not come.
