Government draws sociopaths as files to honey. Money and power are irresistible to these folks, and what better way to protect one’s self from prosecution for crimes committed than controlling the means of prosecution?
The vast sums of money available for pilfering, and the shield from prosecution that control of the justice system gives them is the perfect environment for their nefarious activities. The worse things are, the more money pours in to “fix” the problems they have created.
Drug users and addicts come from all around to buy drugs in the camps.
Addicts have to sell to get the cash to feed their own habits.
All those drugs shot up by street addicts aren't delivered by Santa Claus. There's a system. A flow of drugs through homeless encampments out to the rest of the surrounding countryside.
Drugs and cash flowing like life-blood.
