On the evening of June 5th, a Friday, visitors to Foster Beach on the north side of Chicago may have assumed(猜想，认为) something big was happening. A dozen or more police squad cars parked up and cops milled around(闲逛，四处走动). The beach itself, however, was quiet, with only a handful of(少量的，几个) bathers.
6月5日（周五）傍晚，芝加哥北侧福斯特海滩的游客可能以为发生了什么大事。十几辆警车停在一旁，警察们四处走动。然而海滩本身却异常安静，只有寥寥几名泳客。
Many of Chicago’s beaches have been patrolled(巡逻) by large numbers of police over the past few weekends. The reason why is a fear of “teen takeovers”. That is when hundreds of young people, typically from poorer neighbourhoods, descend on one spot for a party. On the Memorial Day(①背景：Memorial Day 是美国...) holiday weekend, two weeks earlier, a beach at Hyde Park in the South Side of the city was overrun(被占领，泛滥). By the end of it three teenagers had been shot and 53 arrested. The same weekend, at another gathering, five police officers trying to disperse(驱散，分散) a crowd were hit by an 18-year-old driving a car.
过去几个周末，芝加哥许多海滩都有大量警力巡逻。原因是担心“青少年占领”事件：数百名年轻人（通常来自贫困社区）涌向某个地点聚会。两周前的阵亡将士纪念日周末，该市南区的海德公园海滩被占领。事件结束时，三名青少年中枪，53人被捕。同一周末，在另一次聚会中，五名试图驱散人群的警察被一名18岁驾车者撞伤。
Videos from these events have gripped the Windy City of late. “People literally say the words ‘teen takeover’ to me all the time,” says Susana Mendoza, the state comptroller and a mayoral candidate, who wants the police to be given expanded powers to break up gatherings. Larry Snelling, the police superintendent, says Chicago has “to stop making excuses” for unruly(不守规矩的，难控制的) young people. The city’s leftist mayor, Brandon Johnson, avoids the term “takeover”, preferring “teen trend”. He has resisted an attempt to strengthen the city’s existing teen-curfew(宵禁，宵禁令) ordinance. The battle shows how even as serious crime declines, public disorder remains politically divisive.(这场斗争表明，即使严重犯罪率下降，公共秩序问题在政治上仍然存在分歧。)
这些事件的视频近期震动了芝加哥。“人们真的经常跟我说‘青少年占领’这个词，”州审计长兼市长候选人苏珊娜·门多萨说，她希望警方获得更大的权力来驱散集会。警察总监拉里·斯内林表示，芝加哥必须“停止为不守规矩的年轻人找借口”。该市左翼市长布兰登·约翰逊则回避“占领”一词，更喜欢用“青少年趋势”。他抵制了加强现有青少年宵禁法令的尝试。这场斗争表明，即使严重犯罪率下降，公共秩序问题在政治上仍然存在分歧。
