State police have done an internal review of their actions. The department has not responded to a request from The Courant for a copy of that report.

Any Sandy Hook review, experts said, should include evaluating the time it took local officers to get to the school, the decision not to enter immediately and the fact that state police portable radios didn't work in the school, a point Sedensky made in his report.

Valentin said the release of the 911 calls and a complete dispatch tape also would also help anyone analyzing Newtown's response.

"You need to know what the callers were telling the dispatchers and what dispatchers were relaying to the officers on the scene to really get a sense of what the officers encountered," Valentin said.

The Newtown Police Commission meets next week and at least one town official said he expects it will address the police response. The town official, who spoke on condition that a name note be used because of the sensitivity of the situation, said the department needs to answer legitimate questions about that day.

Newtown police have not released their active-shooter policy, which was 10 years old at the time of the Sandy Hook massacre. The town official said it may also be time for police to update that policy.

Kehoe did not return calls to The Courant seeking comment on the police response or Sedensky's report. In an interview with the Danbury News-Times. the chief said the department will "review everyone's actions" that morning.

In his report, Sedensky said that the police response to the school was appropriate and that officers didn't know whether there was more than one shooter.

"They went into the school to save those inside with the knowledge that someone might be waiting to take their lives,'' he wrote.

Newtown Police Union President Scott Ruszyzck said officers have no problem if a review is done because they acted appropriately and aggressively.

Ruszyzck said officers have always known their actions would be heavily scrutinized by the public and by other departments, and that everything they did that morning would be questioned to some extent.

"It is pretty hard to second guess officers, who responded to a chaotic situation like this one,11 months after it happened. Officers took the actions they thought were appropriate on that morning given the circumstances they confronted,'' Ruszyzck said.

Riccio, who was injured in a shooting in New Haven, said police are now trained to run toward the shooter. The theory being the quicker to the threat, the faster you can end the carnage.

"Officers are trained now you go towards the shooting and confront it,'' Riccio said. "That's not a comforting thought to run towards someone with a gun, but, unfortunately, that is the job.''
