MILWAUKEE - Mayor Tom Barrett called for a major overhaul of RiverSplash security measures Monday after weekend crowds got out of control. “This event has transformed itself from a family friendly celebration at the beginning of summer to what this weekend was in many regards a drunken brawl,” Barrett told reporters during a City Hall news conference. Exclusive surveillance video obtained by TODAY'S TMJ4 shows a rowdy crowd even before shots were fired. Fights began breaking out after 11 p.m. In one instance, the video shows chairs and tables being thrown through the air. The staff at one beer tent is noticeably nervous. They bring their cash register underneath their outdoor booth. As RiverSplash closing time at 11:30 approached Saturday night, the crowd showed no signs of shrinking. Bar owner Ryan Wentz feared for his employees. His new bar, Bootleggers, opened Friday just in time for RiverSplash. “We felt that our service staff that was out there was getting unsafe if a crowd was going to rush toward our building,” Wentz told TODAY’S TMJ4 reporter Tom Murray. Chaos escalated. A crowd rushed from the sound of gun shots on Old World Third Street leaving tables and chairs overturned. An 18-year-old was struck in the foot. Unruly party goers threw bottles toward police officers. Even though the street party officially closed, surrounding bars stayed open. “Those bars were required to have bouncers present to prevent people from leaving the establishment with open alcohol,” said Alderman Bob Bauman, who represents the district where RiverSplash is held. “That was not happening.” Bauman threatened to turn down permit requests for RiverSplash in the future, if organizers failed to improve safety. Milwaukee police literally had to call in the cavalry to restore order. It took officers on horseback and Harleys to regain control. Party goers who pushed too far found themselves in handcuffs. “People were pushing and shoving,” recounted Dave Willoughby of Waukesha. “I grabbed my wife and said ‘Let’s get the heck out of here.’” Barrett believes there was not enough security. Milwaukee police officers and private security patrolled the RiverSplash grounds. He plans a meeting this week to discuss limits on alcohol sales. “We will be taking whatever steps are necessary, working with or against those who promote these festivals, if necessary, to ensure these festivals do not turn into what this turned into,” said Barrett. Bar owners like Ryan Wentz know they will have to do a better job of planning. “Really decide what would be the best for the entire festival and the City of Milwaukee to make sure it goes perfectly next year,” Wentz said. City leaders did take a share of the blame for not identifying potential problems in advance. Milwaukee Police Chief Ed Flynn likened the frenzy to an out of control fraternity party. RiverSplash organizers downplayed the rowdy crowd’s behavior, calling it an “isolated incident.” However, they concede security measures need to be evaluated.
