I live in Portland, a city that used to known for being a clean city. In the last 8 years we have had a large increase of car live-in residents and homeless population. I would not call Portland a clean city anymore. In-fact it's far from it. Homeless make up about 3% of the population, but according to a recent article they make up half of the arrests. Personally I've had car camping people outside of my house and we've been afraid of retaliation for call them in and try not to make contact.
I understand that these people have nowhere to go, but cities should create a homeless car shelter of sorts or some other solution other than just hoping for the best of people living on the edge.
