Roosevelt Island Public Safety Report, January 2007-May 2007

Above is the Roosevelt Island Public Safety Report for the months of January-May 2007. The top chart lists what are called "incidents" by type, such as criminal mischief, harassment, graffiti etc., the middle chart lists those "incidents" by building location, Eastwood, Motorgate, Westview etc., and the bottom chart lists "incidents" by post location, Main Street, Seawall Walkway, Manhattan Park complex etc.
Click on each chart to be able to read information.
The report indicates that these statistics represent only those incidents reported. I do not know if that means reported to RIOC HQ, Public Safety, the NYPD or some combination. How do these numbers correlate with the general impression by residents of crime and public safety on Roosevelt Island?
