A second Connecticut town has decided to place armed guards in all its public schools in response to the killings of 20 students and six educators in Newtown.

The Board of Education in Enfield, about 20 miles north of Hartford, voted 5-4 Tuesday night in favor of stationing armed guards at all 11 public schools in town and implementing a series of other security measures beginning next fall. North Branford’s school board approved armed guards in all schools in January.

“We want to throw as many hurdles as we can before an armed gunman can get into a building,” Enfield police Chief Carl Sferrazza said Wednesday. “We refuse in Enfield to accept any casualties in our schools.”
