Why is San Francisco ... covered in human feces?

11. Fully Staffed "Public Assistance Centers."

That's the answer, i think. In a city like San Francisco, about three of them, strategically located. Each would offer:

1. Ample public restrooms, with janitorial services on-site.
2. Shower facilities, available to all, cleaned by staff as needed.
3. Free personal hygiene supplies, donated by retail stores.
4. A clothing exchange, with gently-used clothing donated by charitable organizations.
5. First Aid and Medical clinic, available to both residents and tourists, staffed by a nurse practitioner.
6. Social services, counseling and referral office to provide assistance in finding housing and other resources.
7. Meal vouchers donated by local food service businesses.
8. A hand-picked police officer at a law enforcement desk to take reports and ensure safety.

Expensive? Yes. Worth it? Absolutely. It would not only serve the homeless, but also tourists and visitors, who also often find difficulty in locating needed services and facilities.

That's my idea for dealing with the problem. It's very unlikely to happen, though.
