A member asked:

When should i call 9-1-1, if there is a shooter in the building?

A doctor has provided 1 answer

Call ASAP: A mass shooting typically continues for five minutes before anyone calls emergency services. If you have other people in the room to barricade the door, calling immediately can be a big help. Once they've been called, law enforcement typically arrives within three minutes.
