I wish I could answer your question.
I haven’t heard WHY there were only 165 detained.
But, I’m happy that something is being done.
BTW, in Portland, this is VERY unpopular.
There are a lot of libs having fits over this.
It’s a beautiful sight. ;o)
My guess would be it has to do with the number of shift workers available, whereas just under 600 workers has to do with all enrolled workers.
