The Most Wanted USA Android app links to open data feeds provided by various police and sheriff departments all over the United States.
Most Wanted USA can only provide live feeds of police activity and arrest data where the agency has an open data policy.
Users in areas that do not allow open data can still take advantage of Most Wanted USA which is also an excellent recourse for local most wanted and active warrant police or sheriff websites.
