It takes time to call 911, and for law enforcement to arrive. And when they do, information is limited.
The Albany County Sheriff's Department thinks it has a solution. It's called Mutualink, and the department is willing to install it in schools for free.
Right now, Mutualink is a pilot program in the Voorheesville and Berne Knox Westerlo school districts.
The system not only links the school with the sheriff's department, but with several local response agencies.
Mutualink can be used in many situations, including not only active shooters, but natural disasters and even vandalism.
