The FBI (Click download link to obtain) study evaluated a number of indicators in mass shootings from 2000 to 2013.  This study revealed during the 13 year period –  160 shootings, with 486 individuals killed and 557 wounded (figures not including shooters’ injuries or deaths).  in an earlier article, there have been 87 shootings since the Sandy Hook School mass shooting.

 These 87 shootings have taken place between December 2012 –  October 2014;

which one organization reflected on by stating:
“How many more before our leaders pass common-sense laws to prevent gun violence and save lives?”

 we at Keys’ ask a different question:
“How many more before our schools’ learn techniques to identify these Students, in need of immediate help, and to stop this violence and save lives?”

According to the FBI; their goal for this study was to “provide federal, state, and local law enforcement with accurate data so they can better understand how to prevent, prepare for, respond to, and recover from these incidents.”

A Mass shooting is identified by the FBI as an “active Shooter incident” (ASI).  The FBI defines an ASI as: “individual(s) actively engaged in killing or attempting to kill people in populated areas (excluding shootings related to drug or gang violence).”

Now let’s look at the FBI’s findings through their evaluation of the Mass shootings – “Active Shooter Incidents” between 2000 to 2013.  They found:

  • Seventy percent of the incidents “occurred in either a commerce/business or educational environment,” the FBI said.
  • “In at least nine incidents, the shooter first shot and killed a family member(s) in a residence before moving to a more public location to continue shooting,” according to the FBI study.
  • PDS2[1]Most of the shootings were carried out by males. Only six of the “active shooters” in incidents during that time period were female.
  • In 40 percent of the cases studied, the shooters killed themselves.
  • Cases Studied
    • Among the incidents studied by the FBI for the report was – the Sandy Hook Elementary School shooting in Newtown, Connecticut, on December 14, 2012. Shooter Adam Lanza, age 20, killed 20 children, ages 6 and 7, and six adults at the school before killing himself.  Prior to entering Sandy Hook the shooter killed his mom in their home according to police.
    • Another mass shooting studied was the Aurora, Colorado, movie theater shooting in 2012. Twelve people were killed and 58 wounded. Accused shooter – James Holmes pleaded not guilty by reason of insanity to the killings; his trial begins next month.
    • In 2007, Virginia Tech student Seung-Hui Cho shot and killed 32 people and wounded dozens more in a classroom building and a dorm on campus before killing himself.
    • Maj. Nidal Malik Hasan killed 13 people and wounded 32 at Fort Hood, Texas, during a shooting rampage November 5, 2009. He was convicted and sentenced to death.

Why are we missing these “Active Shooter Incidents”?

The study reflected a “principle” that many Crisis Response Professionals understand and which Keys’  imparts to those we train –  Agencies/Schools will be on their own until the Crisis Response teams arrives.

“Recognizing the increased active shooter threat and the swiftness with which active shooter incidents unfold, these study results support the importance of training and exercises — not only for law enforcement but also for citizens.”
