>Yes I agree that makes sense - but the rule says "No person shall conduct or participate in assemblies or demonstrations or engage in other expressive activities". Its the "other expressive activities" part that I have an issue with - heck that can mean just about anything! What next? Wave goodbye to someone - hey that's an expressive activity - so the BART cops come and arrest or kick you out? ...oh my mistake....decide to shoot you..

Posting ads expresses the poster's wish to sell - it's an expressive activity - arrest all advertisers.
