So Gene Ward wants to create a 160-acre ghetto as a "safe zone" or shantytown for homeless. Maybe put barbed wire around the concentration camp to keep them in?  

The question is, once we build it, will they really come?  The homeless seem to prefer squatting on beaches and in parks and sidewalks.  They love to be where the action is; where they can get free water and electricity for the TVs and air conditioners with which they furnish their tents.  Where they can get shopping carts, collect cans for the deposit, and have plenty of people passing by whom they can harass for handouts.  Let's remember the song about soldiers returning after World War 1:  
"How Ya Gonna Keep 'em Down on the Farm (After They've Seen Paree?)"
