VIDEO: Avoid, Deny, Defend: that's what one volunteer fire department in eastern Iowa wants to teach others to do while under an attack. Training sessions are not unusual for the West Branch Fire Department. The meetings happen at least once a month. Sandy Heick leads all trainings. But Wednesday night's meeting had a different twist. She taught her fellow firefighters the Civilian Response to Active Shooter Events, known as CRASE. The training looks at previous mass shootings to see how people successfully escaped. First, people should try to avoid the situation, or run away.
