Actually there are many things that could have, including:
1. if the school had decent security guards back then, enough to realize that a freaky guy they've never seen before walks in with a suspicious bulge from a gun in his coat;
2. If the male students had tried to stop him instead of just running away when Lepine told them to leave. I know: some of them would have been hurt or killed - but at least this scumbag wouldn't have as big a tragedy in his name.
Everything now can only be a game of "What if". Doesn't change the fact this was a horrid tragedy.
