Rather than attempt to control the masses of tourists and business travelers entering the country from all sides – essentially an exercise in futility in Switzerland – the country decided to focus police resources specifically on security threats. By joining Schengen, the Swiss police also gained access to the Schengen Information System and other important European databases on criminal suspects, stolen cars, and more.
随后，瑞士等非欧盟国家选择加入申根区，这凸显出开放边境的巨大好处，包括安全方面的好处。瑞士没有试图控制来自四面八方的大量游客和商务旅行者进入本国——对瑞士来说，这基本上是徒劳的——而是决定将警察资源集中起来应对安全威胁。加入申根后，瑞士警方也得以进入申根情报系统和疑犯、失窃车辆和其他方面的重要欧洲数据库。
