A 14 year old gunned down four people at a Georgia high school Wednesday.
The tragedy left America to once again come to grips with a problem unique to itself.

School security expert Dr. Ken Trump says it's a problem with no one solution.

"It takes a balance of prevention, to preparedness and response, partnerships with your first responders and school community and most of all though, engagement with your students, staff, parents and school community to create a culture of school safety," Trump said. 

Trump believes a critical piece we're missing is a change in focus.
He sees too many metal detectors and security cameras, and not enough practical prevention measures.

"We're winning on the target hardening, we have all the bells and whistles and shiny objects there, but we're losing the game because we're not spending time to train our staff, do professional development in school districts with school safety in addition to curriculum."

In the 25 years since Columbine, many psychologists say the collective psyche has become desensitized to mass shootings - many of which have happened in places other than schools.

"It's a coping mechanism," said Valley pediatric psychologist Dr. David Chiarella. That coping mechanism is one he fears we have yet to see the true impacts of.

"Will it lead to more emotional callousness, will it lead to a lack of remorse, will it lead to even more violent behavior? It's kind of scary to think about," Chiarella said. "We need to talk about it. We need to actually share our feelings and rather than becoming numb to them, we need to share them with other people that feel the same kinds of feelings.".

Chiarella added that the Georgia shooting should be also be a call to action to get involved in efforts for change.
