Earlier quoted context omitted.
If you really want to help folks, get them a home and treatment first. Before inflicting your "utopia" on us transit riders.
How are they supposed to get to treatment if there isn't a transit system to help them with that? And of course folks should have housing and treatment. The reason we have issues in some areas is because they aren't doing that. It doesn't meant that we shouldn't provide public transport to everyone that wants it, though. It is quite possible to do more than one thing at the same time.
They are not going to inpatient treatment and housing voluntarily on the bus. Is the guy screaming obscenities at the air even aware of all his treatment options? They often need to be coerced, so trained individuals need to bring them there humanely.
If they are just having bad luck, they will mostly likely need their belongings brought with them. Both these things point to van transportation with trained drivers. Not the city bus.
You might spend some time thinking through the problem rather than casting aspersions. But one of those is easier, isn't it?
