Street-corner oratory could also present its share of problems. Chief among these was the policy of local law enforcement authorities, who sometimes saw in radical political discourse a form of incitement to crime and violence and a threat to public order. Additionally, large street corner crowds listening to "soapboxers" would often obstruct public walkways or spill into public streets, creating inconveniences to pedestrians or vehicular traffic alike. Consequently, local authorities would often attempt to restrict public oratory through licensing or prescriptive banning.
