No doubt someone may have found the performance annoying–busking is busking whatever the caliber of the performer. That said, there is nothing in the article linked above that suggests that the police were responding to a complaint. That is, it’s unclear whether they saw an opportunity to protect he streets from opera but were provoked into arresting the singer when she refused to shut down her amplified orchestral accompaniment.
Truth be told, we’re torn on who we should support in this story. On the one hand, we would prefer to not be bombarded by amplified sound. On the other, we wonder whether the police are normally as diligent when dealing with noise criminals. Adding that we wish the cops were as vigilant with motorcyclists sporting aftermarket tail pipes as they are with desperate opera singers carrying amplifiers.
