Experts in active shooter response training in Central Texas are closely monitoring the situation in Connecticut and will analyze how law enforcement responded to this tragic event.
"When a gunman walks into an elementary school, that is the weakest point in our society," said Terry Nichols, the assistant director of the Advanced Law Enforcement Rapid Response Training, or ALERRT, center at Texas State University.
He's keeping a close eye on the mass school shooting.
"We can do everything right, the teachers can do everything right, the school district can have all the plans in the world, law enforcement can be there in seconds and we can still have a significant body count," he said.
But even so, he and other active shooter response experts will analyze every part of this situation and take a look at their training procedures.
"Is there anything we can tweak? Do we work closer with the school districts with model policies out there like the standard response protocol?" he said.
The Standard Response Protocol was developed by a father who lost his daughter in a Colorado school shooting. His protocol is being adopted by school districts around the country.
"You have lockdown, lock out, evacuate or shelter, four simple terms that a kindergartner can learn," he said.
Nichols says it's vital to have these procedures in place because of how vulnerable people are inside school buildings. In addition to looking at response procedures, this incident will likely spark a conversation about what needs to change when it comes to school security.
"It's just tragic if we have to fortify our elementary schools and make them like a fortress. Our society should not be that way," he said.
