Using a ccw in a bank against an active shooter

I carry every day and I’m the branch manager of a bank. In a robbery situation I will comply and get them out as soon as possible. However, after things like repos or even terminating an employee, I see the potential for an active shooter.What’s your experience on using a firearm if it’s against the employee handbook but in an active shooter situation? I compare this to a teacher stopping a school shooter with their handgun. Thoughts? via /r/CCW https://ift.tt/2SfXeeG
