Chattanooga police changing policy on how they will handle gun violence
CHATTANOOGA (WDEF) – Chattanooga Police Chief Fred Fletcher joined Mayor Andy Berke on Monday to announced a new policy for dealing with gun violence.
The Chief did not reveal details on what is changing.
But it involves technology and intelligence gathering.
And it requires more officers to carry it out.
Today the mayor announced that they are adding 14 new officers to carry out the initiative.
The chief will announce details of the new initiative in the coming days.
The new conference comes a day after another violent weekend in the city (though shootings had actually dropped over the last few months before this weekend) and as the Mayor faces re-election.

What Is NIBIN and How Is It Used?
When a gun is made, the manufacturing equipment etches microscopic markings — somewhat like fingerprints — onto the gun’s metal parts. These markings, called tool marks, are transferred to a bullet or cartridge case when the gun is fired.
When law enforcement investigates crimes in which firearms are used, ballistic imaging of such bullets and cartridge cases can be important in solving crime.
NIBIN is a national database of digital images of spent bullets and cartridge cases that were found at crime scenes or test-fired from confiscated weapons. The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) manages the system and provides the equipment to crime labs around the country.
A firearms examiner uses ballistic imaging to convert the spent rounds into two- or three-dimensional digital images that are uploaded into NIBIN. NIBIN can be searched for possible matches — that is, other rounds that have similar tool marks and thus may have been fired from the same gun. After a possible match, or “hit” is identified, the crime lab secures the actual spent round(s) and compares them under a microscope to confirm the hit. Then, the lab sends information on the hit (a hit report) to investigators.
A NIBIN hit report has many potential tactical and strategic uses for law enforcement. Law enforcement investigators can use it to link crimes, which can help to identify suspects. They can also use it to understand patterns of gun crime, such as gun sharing and trafficking.
Chief Fletcher said that his department and other agencies put more officers on the streets and behind the scenes in an effort to keep the violence from escalating.
He says the emphasis will continue for several days.
