The adults weren't completely innocent. They were served a legal search warrant and instead of the doing the sane thing, they hold up inside their compound. After surrounded by police a sane person would surrender. They were delusional and caused the deaths of their own children by not letting the cops serve a warrant.
If the cops come to my house to serve a search warrant and I hold up inside with guns and don't let them in their is only one end result. Eventually they are coming in and if I hold out through the tear gas and whatever else they use to try to flush me out, then yeah, eventually I'm gettin' shot and I'm gonna die.
