Use of Social Media Networks and Mobile Phone Applications for Reporting Suspicious and Criminal Activities on Mass Transit [open pdf - 1MB]
From the thesis abstract: "The threat of terrorism remains in the forefront daily, and public transportation systems remain a preferred target for terrorist attacks. Mass transit customers have long served as the 'eyes and ears' of the public transportation environment. In support of the Department of Homeland Security's See It Say It campaign, mass transit customers contribute to this effort by reporting suspicious and criminal activities on subways and buses. The use of social media networks and mobile phone applications by mass transit law enforcement is slowly evolving as a tool for reporting suspicious and criminal activities on subways and buses. By reviewing the data and current use of social media networks and smartphone applications such as by mass transit law enforcement agencies, this thesis demonstrates that citizens want to play a role in assisting law enforcement in solving crimes. Mass transit law enforcement agencies can leverage community involvement and reduce crime by providing customers with an anonymous means for reporting suspicious and criminal activities. However, whether the use of social media networks and smartphone applications have resulted in an increase in reporting suspicious and criminal activities and a reduction in crime is unresolved, warranting future study in this area."
