What got through? My understanding is there were no meaningful hits--some of the ballistic stuff wasn't intercepted but came down where it didn't matter. And you don't know if that means a miss or means they didn't fire--Israel has gotten quite good at plotting where a ballistic weapon is going to come down and deciding whether it's worth expending an interceptor on it.
The only casualties I'm aware of were from the debris of a successful intercept. It's not like a war game, when you kill something it doesn't just turn into a boom and disappear.
