It's weirdly both such a big number and such a small number.
15k is a ton for many people and probably well more than the inconvenience this one guy suffered.
But it's insubstantial compared to the cost of this case turning into a class action and getting the city to actually have to change something, and it sounds like it's insubstantial compared to the total harm of this program. Especially cases like the woman who was nearly arrested.
