Gwinnett Police are using new technology to make a big boost in busting bad guys.

During a trial three-month period, the number of warrants served in Gwinnett increased 397%, according to the Gwinnett Daily Post.

The force now plans to use the LPRs full-time, although it won't completely ditch the old fashioned way of looking suspects, including knocking on doors and interviewing witnesses.

The LPRs were originally supposed to be used to track sex offenders only. But their use is now expected to expand to anything from a misdemeanor traffic citation to a felony.
