Regarding "Tent City" in Amarillo, I see both sides of the issue.
The city has laws designed to protect citizens. Conditions at the camp were both unsafe and unsanitary.
Now to the real question - where did the people of the camp go? Out of sight out of mind. They are still out there. Open your eyes. They just aren't in one viable location. They still need help - many of them psychiatric help.
The issue didn't go away - it just spread out.
