There were fewer people and only one report of violence. But the relatively uneventful Mifflin Street Block Party on Saturday did little to dissuade Madison?s top cop that the decades-old event needs to end. An estimated 5,000 people filled porches, homes and yards in a two-block section of West Mifflin Street. Unlike last year?s sponsored event, no drinking was allowed on sidewalks or the street. That resulted in Madison police as of 7:45 p.m. Saturday arresting and citing more than 400 people.
