@Flipboard @ProPublica Around here encampments are often far from tidy.
I've participated in cleanup efforts in my neighbors forest. It is hard, dirty, dangerous work. None of the "owners" were present. Broken glass and needles (and amazing numbers of bicycle parts) were everywhere. I've had to remove leaking bottles of urine (used, I have heard, in drug production) and my wife had to use a pitchfork to move rodent infested, almost liquefied bedding. Clothing is often interfused among rotting debris and is hard to distinguish from those debris. Much of the material is properly characterized as hazardous. None should be touched without protective gloves, boots, and facemasks. It's not a situation where procedures for marking things and nicely packing them up for storage are going to be practical.
I have indeed seen prescription drug containers bearing names, but never money or food stamps. Around here there are far more plastic tarps used as lean-tos than there are tents.
