Well, we do know by now that according to Lavender the death of 10-15 civilians for a low level Hamas fighter is tolerable, for high level commanders 100 civilian deaths are still just fine. Also, Lavender prefers hitting apartment blocks because the targeted people are easier to find when they’re with their families.
