The radical progressive Left city council and mayor make is so "sweet" (easy) for the drug users to come to Seattle and be coddled. So they come.
They are coddled in the sense that the cops don't usually harasses them, they seldom arrest them. When they do, they let them go the same or next day. The cops know these people by their first names. They're told to treat interaction with these folks like it's an intervention of some kind.
But what it really has become, is no intervention at all. Period. Let them do what they want.
And the city leadership endorses this, accepts this and focuses much of their resources on a problem of their own making. And what things they do do, just enables the problems and the drug use and homelessness get worse. It's spiraling out of control without any adults in the city running the show.
