Let's talk about actions, not theories:
1. We need to build basic housing units to which "homeless" people can be assigned.
2. We need to enforce vagrancy/nuisance laws. This includes clearing out illegal homeless encampments and arresting people who sleep, defecate or discard needles on public property.
3. First time offenders will be let off with a warning. Multiple offenders will be prosecuted and sent to appropriate treatment centers.
Any questions or alternative actions?
Every time some group builds "basic housing units" for the homeless, they are trashed beyond use in a matter of days.
Most homeless shelters call for codes of conduct that the people who should use them refuse to follow.
