Newtown survivors weigh in on PA school workers carrying guns

Teachers and staff who survived the Sandy Hook school shooting are having a say in Pennsylvania politics.
Lawmakers in the state are considering a bill to let select people carry guns on school grounds.
Opponents read a letter written by survivors from the shooting in Newtown, saying guns wouldn't have changed what happened on the day of the attack.
The measure is unlikely to get final approval despite getting some support from Pennsylvania politicians
