This is actually an interesting problem if people gave it a minute. Here's the initial conditions: We don't lock up mentally ill people anymore in California because "patient rights" including the right to non-neurotypical. This results in mentally ill people wandering the streets. They are too sick to respectfully use commerical establishment bathrooms, so they rely on public bathrooms. Since there is a shortage of those, they end up using the street. So SF wants to build an indesctructible public toilet for them so they don't use the street, which turns out to be hard because the mentally ill are often clever and find ways to make it a nightmare for everyone, so it ends up costing 1.7 million dollars and take a long time. What would you do?
