Many questions remain about
how the gunman was able to enter the Texas elementary school.
According to officials, an armed school resource
officer was the first to encounter Salvador Ramos at Robb
Elementary School, but no
shots were fired, yet, there are growing calls for more armed guards at
schools.
An estimated 20,000 armed school resource officers are on duty, paid for by "close
to $1 billion" from state and local governments hoping to stop
violent attacks.
But are they effective?
"Listen, I'm a parent
of high school kids," says Marc Schindler, executive director of
Justice Policy Institute. "If there was evidence to show that school
police officers would make their schools safer, I would be all for it! But at
the end of the day, there is literally no evidence to show that police in
schools make schools safer."
Defenders of armed officers in schools say they must
be seen as just part of a much larger, coordinated effort to make a difference.
