You are right My Memory is off. However, reading what did happen sounds worse than what I thought happend!

"In 1985, the group made national news when police dropped a bomb on the Osage house from a helicopter in an attempt to end an armed impasse. The explosion killed 11 people, including five children and the group's leader, John Africa. Only two occupants survived, Ramona, an adult and Birdie, a child. In addition, 65 homes were destroyed as the entire block burned.[2]"

Apperantly I blended the Police shoot out with the SLA and the Move Incident.
