I watched the film this evening. I guessed it was just released on YouTube. The film was about the homeless problem in Seattle. It was clear that these people are also drug addicts. The point is that by allowing this homeless problem to continue, the city is inadvertently contributing to the overall problem. Those that are paying thier way are reaping the collective criminal reward that this homeless element leaves in its wake.
According to the film virtually all of these "homeless" are either drug addicts or mentally disabled.
As these people break the law either by stealing or simply by executing the lifestyle of living on the street, they are arrested and then released the same day... Even some violent crimes are not prosecuted.
This ineffective judicial system is seen as the root of the problem.
...many aspects of your statement are similar to the problem at the southern border.
