I've seen investigative reports like that, and would like more. Around here they often rent an apartment together, and hop in a van together each morning to be dropped off at their bumming spots...
The only guy I give money to sleeps in a ratty minivan with his old lady, parking in various spots around this area (I've seen him for almost 5 years, now). He buys a stack of newspapers though, and hands one out with each donation. Almost like a business transaction. I don't normally read the paper, but I'll buy one from him any time I pull up next to him.
