Human waste shuts down BART escalators

I'm sure there are ways to design the environment so that the homeless don't relieve themselves on the escalators (which is what I'm assuming is happening).

First off, how about leaving a washroom open?

Though I know many of the homeless suffer from mental illnesses, I feel somewhat confident that they don't want to crap in public. Could be why they are using the escalators. The escalator siding probably offers them some small bit of privacy in an open station (again not from SF, so don't actually know what the area looks like).

The idea that the cops can't ticket the homeless unless they witness them, somewhat misses the point. What is a homeless person going to do with a ticket? Why would they care if they got a ticket they likely can't pay, and what other options do they have.

As a friend here just mentioned, they would probably appreciate a ticket as then they'd have something to wipe themselves with.
