FORSYTH COUNTY -- The FBI released a study of 160 active shooter incidents that occurred in the U.S. between 2000 and 2013. Officials have studied each and every situation to come up with active shooter training scenarios.

"We have, unfortunately, like any other community in America, we have the risk. There is no community that is safe from harm," said Scott Cunningham, Kernersville Police chief.

Strong words from the Kernersville Police Chief before the FBI began the ALERRT or Advanced Law Enforcement Rapid Response Training program.

"Should something happen we've got the knowledge to minimize the risk of injury and to reduce those injuries should something happen. This training is not just someone decided to cook up, and let's draw up a couple scenarios this is scientific and database training," said Cunningham.

Since the 1999 shootings at Columbine High School, the FBI has studied more than a dozen active shooter incidents in the U.S. Officials cannot detail the ALERRT scenarios and techniques but do say, if they get a call of a possible active shooter, they must enter the building immediately.

"So they know exactly what they have, what they need to make that entry to get rid of that threat but at the same time to do it safely and also to establish some incident command on scene so that executive management and the police structure as a whole can better respond and provide more resources as soon as possible," said Adam Scholtz, FBI ALERRT instructor.

Officials advise citizens to always pay attention to your surroundings and if need be, use the run, hide, fight method.

"You should deny entry, find a safe location, you should barricade yourself in that location and try to deny entry to that person who may be a threat to you. If you can't do that citizens need to be able to defend themselves in any means necessary in order to provide time for law enforcement to respond," said Scholtz.

More officers will be ready if needed. In the past year across North Carolina, the FBI has trained more than 300 officers.

In March 2013, the FBI announced that ALERRT is the national standard through which they are training their agents. More than 70,000 officers have been trained in the program.
