The operation was introduced a couple of years ago in an effort to reduce violent gun crimes between the area of NC 147, N Mangum Street, Miami Boulevard and Hoover Road.
Police said violent gun crime is down by 1 incident in the last year -- from 101 to 100. Shots fired calls are also down from 278 to 214, along with drug calls from 580 to 506 and prostitution calls from 80 to 73.
"At some point you have the law of diminishing returns .. we can't think that it will just keep going down, down, down to zero that is not realistic," One official with the Durham Police Department said. "We see a downward pattern, we are glad to see a downward pattern. Do we expect to see at some point one year we may see it go up a little bit, we may."
Overall violent gun crime is down about 46 percent in the last six years of Operation Bull's Eye, according to police.
Durham Police Chief Jose Lopez was not present at Thursday's meeting.
