It's been almost a year since a gunman entered Connecticut's Sandy Hook Elementary School, killing 26 students and staff.
When the emergency sounded everyone was kept inside the building.
That's known as a lockdown and many schools including those in Cranston have lockdown plans.
A former student tells us how they practiced emergency drills.
"You could not leave the classroom until the alarm went off, and I don't think that is a good idea at all, because if there was a gunman or anything, its very easy to get into a classroom and do whatever they wanted to do," said 2012 Cranston East graduate Brandon Iacobucci.
Now Cranston Police are implementing a new emergency plan known as "A.L.I.C.E.," instead of lockdowns, it would let students and staff members try to safely evacuate the building.
ABC6 Chief Political Reporter Mark Curtis said, "One reason for the policy change? Recent studies that show that school shootings are usually half–way over, by the time police arrive.
The theory is, if students and staff scatter, they are less of a target.
"Just get the kids out of the school. That should have been the plan all along. The problem is that the guy is in the school. Just get him out."
But some parents we spoke with are skeptical, and want police to have flexibility.
In some incidents, the gunman has been on school grounds, but not inside a building.
"Try to contain the gunman wherever he is. And if he is outside, then I would have a lockdown for the children to be inside the building," Frank Mandella, a Cranston School parent.
Cranston Police and school leaders will have more public forums to discuss their safety plans.
