A few of my friends, Papilicous & Loose Lips Sink Ships, posted photos of a homeless guy (presumably) taking a cell phone picture of Michelle Obama in a soup kitchen. They were a little angry that the homeless guy had a cell phone (presumably because it was expensive). I totally get the frustration, but lost in the immediate response, is the fact that cell phones keep those folks tethered to society. It's easier to get a job or apartment, because they can be called back. They can call the police if they are in danger.
Communication is a basic human need and it can help get these people back into a productive life style.
