People don't understand the addict mentality. Live in a box? Check. Defecate under a street lamp? Check. It's worth it for the ability to stay high. The high of the addict is all that matters. Everything else is secondary.
And when these dregs of society find a bunch of lazy cops, and lazy city administrators, and liberal fools, all of whom enable them to stay stoned, said addicts will flood to that city. LA. San fran. Portland. Seattle. Juno, Alaska. It doesn't matter. They'll find a way.
When Orange and Anaheim shut down the 700 person homeless camp that had erupted along the Santa Ana River Trail they found that the homeless were roughly 1/3 drug and alcohol abusers, 1/3 mentally ill, and 1/3 criminals. With the three groups blending in many cases.
There weren’t any illegal aliens, probably because they have long been used to living 20 to a house to share the rent. Our local cities turn a blind eye to the overcrowding and let neighborhoods go to hell.
