I think you make a good point, alluding to one I made 30 years ago when the Mall was opened to car traffic. All of the places you mention are private property. As such, property owners can EXPEL without trial people for smoking, cursing, being disruptive, panhandling, hanging around, looking suspicious, proselytizing, gathering petitions, sleeping, littering or being a nuisance. But downtown is public property. People have many more rights there. Those include the right to smoke, curse, panhandle, hang around, look suspicious, gather petitions, proselytize and just generally be  a jerk - all protected. Are you suggesting we treat public space like private space and regulate it more strictly?

If you believe public space should be regulated like private space, do you believe this space, which is a private space owned by the RG should be regulated via the Civil Comments process?
