Arena security

Many sports arenas now offer a number where patrons can text report security concerns, like drunk or unruly fans, or safety issues like spills. These programs have been praised by patrons and security personnel as more effective than traditional methods. For instance, the patron doesn't need to leave his seat and miss the event in order to report something important. Also, disruptive fans can be reported with relative anonymity. "Text tattling" also gives security personnel a useful tool to prioritize messages. For instance, a single complaint in one section about an unruly fan can be addressed when convenient, while multiple complaints by several different patrons can be acted upon immediately.
