So where are these homeless losers going to go if banned in the daytime?
How about City Hall.
In the minds of the idea-people, the guilty party would just walk around/linger....near their push-cart or shopping cart. Then re-camp as night falls.
What I’d suggest is a $20 nuisance-camping fee on public property at 6 PM. You send out 20 nuisance officials (with ample police) to collect the fee each night. You argue or refuse....cops take you for a 96-hour stay in jail (where you get zero access to drugs). People would then vacate the city within a month because of the cost involved.
They’ll ride around on the train, taking up multiple seats, making it smelly and filthy and panhandling the passengers, just like every other city.
Somewhere else.
Having to strike camp every morning is a mighty PITA. They will find a more hospitable city, if it is really enforced.
But the new problem is going to be people living in cars -- non-running junk cars will proliferate greatly.
libraries....the metro...or bus lines....
MOre to the point, who will Portland get to enforce the ban?
