Seems to me that he is noting how the police often times harass the homeless with these charges and how a large number of homeless are mentally ill and that simply processing them through the system over and over does absolutely nothing about the issue.
I agree. Being an ex officer I am sure he is very well aware of how all of this is done.
He is telling the citizens and the politicians to deal with the actual issue and quit expecting the police to do over and over what doesn't work.
SF is a liberal mecca. The DA, citizens, politicains are all liberal and have done nothing and have no plans to do anything. Im not surprised at the amount of homeless in CA nor am I surprised at the increased lawlessness and inequity occurring out there. They don't care.
