I’m really in 2 minds whether to post this. On the one hand it is not for us to sit and preach, saying what should or could have been done differently to prevent these tragedies. Especially when there are grieving families with an unreparable hole in their lives.
But on the other hand, I think it behooves us to take responsibility and not conveniently stick our heads in the sand with misplaced bitachon. Seforim that discuss bitachon and belief in Hashem’s hashgacha are clear: If you dont take care of your life, you cannot rely on Hashem to save you. You are not a Baal bitachon. You are a fool.
You decide, mods, but I think the OP is right. Cheers, please – look after yourselves. Don’t swim anywhere with no lifeguard. Water is a monster that consumes too many victims who think they are cleverer than everyone else.
